Re: "The orbs I got for the various matches were... I think it is unfair of you to say that these were all HUGE ORBS..."
I didn't in any place say that they were "all" huge orbs. What is true though, is that if you allow orbs out to 1° 30' of arc, you are (obviously) potentially considering midpoints with huge orbs. If every point is "allowed" a 1° 30' orb, then it should be obvious that each midpoint is carving out 3° (1.5 applying, 1.5 separating). Multiply that 3° by the number of points and midpoints (and then by the number of aspects being considered) and the zodiac is mostly full...just by chance.
You don't have to agree with me just because I look at it statistically, but it would be somehow wrong of me to not comment on what to me is an obvious mathematical error. If you've read the Marr book, then you'd know that, in natal astrology (which normally uses LARGER orbs than are considered in transits--- ie. two planets 6° apart are considered conjunct in a natal chart, but you'd never (I hope) consider a transiting factor with an orb of 6° as relevant) he is suggesting for aspects other than the conjunction and opposition, an orb considerably smaller than you would imagine (single digits even). In Transits, to have a reliable relevancy, it would be less.
Re: "Now the reason I use this method, is that suppose we use 22 events via Polaris but only 10 of them check out using Primaries, Secondaries, Solar Arcs, Solars etc...."
Before we go further unnecessarily, let's stop right there. If you only have 10 events checking out, out of 22, then the rectification can already be seen to be wrong. Midpoints won't be necessary for that, unless you're wanting to get a false sense of security. The Primary Directions, themselves, should have an 80% hit rate OR MORE and with very, very tight orbs. In your example, it's less than half.... ie. wrong birthtime.
I won't mention any names or dates as the person is entitled to their anonymity, if they choose, but I just did a (free) rectification for someone on this forum. With the 11 events that I have used, they ALL have relevant factors in ALL the systems (Primary Directions, Secondary Progressions, PSSR, and Age Harmonics). Some are more clearly stated than others, but all of them symbolically fit the events.
Re: "So we are left with NO METHOD to check if the Polaris rectification is correct."
Before I would ever use midpoints to try and justify the rectification, I would have left two events out of the rectification, performed it, and THEN checked those two missing events across these systems to make sure it was right.
For the rectification listed above, the person was a bit skeptical (a good thing) and wanted me to do the rectification and THEN give me a very major event in order to test the rectification and to see if (as I had said many times) the Topocentric Primary Directions are reliable in symbolism for future events and out-of-sample tests.
I completed the rectification and sent the results. I was given the major event, which was "meeting a love interest" (to them a soulmate, so not just a love interest, but a very special one!)
What Topocentric Primary Directions match the date given?
Jupiter conjunct the 5th (0° 9')... ie. the planet of social expansion and good tidings exactly conjoining the cusp that says romantic interest!
Node conjunct MC (0° 8')... ie. individual relationships and the establishment of unions based on shared inner understanding!
The ONE TIME when this occurred astrologically is the ONE TIME when it occurred in the life.
This is corroboration, short and to the point, beyond what a page of X = Y/Z could provide.
From reading your comments, I can only deduce that there are elements of this process that you aren't understanding completely and that it is working to your detriment in doing rectifications with Polaris. As Polaris isn't cheap, I suggest (to get your full money's worth) that you perhaps contact Isaac and perhaps he can increase your efficiency with his program and these methods.
Re: "Please don't use that stupid argument about HUGE ORBS again."
The argument only appears stupid. If you use transiting midpoint pictures out to 90' of arc, we can "prove" that on the day of one's Mother's death, they instead had a child.... we can "prove" that on the day one's Brother was born, they instead were in a terrible accident, etc.
The Point: If we can show so many events that didn't happen, based on the multitude of midpoint pictures, it should be obvious that the midpoint pictures will be lacking when trying to prove CONCLUSIVELY that any particular event did, in fact, happen.
One last attempt to push through on this... Let's say that we have a terrible event that happened in someone's life... perhaps, they were in a car accident that left them widowed. We look and find (among 35 other midpoint pictures) that Pluto = Saturn/Uranus. Now, if the event happened on May 15th of 2009, and we allow up to 90' of arc, then that midpoint picture is active Feb, Mar, Apr, May, Jun, Jul, Dec of 2009 and Jan, Feb, Jul, Aug, Sep, Oct, Nov, and Dec of 2010! Get it? You can pretty much use that midpoint picture to explain some terrible thing happening virtually WHENEVER over a two year period. And what do we make of the (normally very positive) Uranus = Sun/Jupiter (orb 0° 2') that happened in the middle of May? What do we make of the 20 positive midpoint pictures that are COINCIDENT with this calamity? In the middle of a girl's dream wedding, the crown of her LIFE, what do you make of the 20 negative midpoint pictures at the same time?
What you really need is something mathematically conclusive. If you are finding the correct aspects (for the event) relatively clearly stated across all of these systems, the mathematical odds are very small that they would all line up for the wrong birthtime.
As a (real world) example for Birth of one's Brother...
The Topocentric Primary Directions show Jupiter conjunct the IC (0° 2')...check.
The Progressed Sidereal Solar Return shows Node conjunct Mercury (0° 5')...check.
The Secondary Progressions show Jupiter sesquisquare Node (0° 5') and IC conjunct Sun (0° 7')...check.
The Age Harmonics show AH Mercury conjunct AH Vertex and AH Sun trine Node...check.
The Transits show Jupiter (r. 3rd) square Moon...check.
Another (real world) example for meeting one's future wife...(from same rectification)
The Topocentric Primary Directions show Venus semisquare 5th (0° 2')...check.
The Progressed Sidereal Solar Return shows Venus inconjunct Asc (0° 1')...check.
The Secondary Progressions show Jupiter sextile Venus (0° 0') and Moon trine Sun (0° 3')...check!
The Age Harmonics show AH Sun trine AH Node and AH Venus conjunct the MC...check!
With all due respect, Halina, this is the way to check a rectification...the mathematical odds that all these systems would line up symbolically perfectly in all of these systems at the timing of the event for multiple events is quite small.
The chances of finding thematically correct midpoint pictures within 90' out of 36 or more midpoint pictures using the wrong birthtime is quite HIGH.
I can't state it more plainly than the directly above two sentences...
