Interesting. I had a student who, before flying with me, had accumulated about 12 hours before family and life happened and he took long break (like 20 years). I ended up flying with him another 10 or so hours as he had pretty much forgotten everything. He ended up soloing at like 23 or 24 hours after the stage check. Guess that makes me a bad instructor for wanting him to demonstrate 61.87(d) items with a high level of competence before soloing. Mind you, he ended up finishing his private around 49 hours which, compared to the rest of my 40+ year old students, was quite impressive.

Obviously simguy has never been am instructor before to make such a ridiculous statement.

Pretty sure he is talking about all at once. 20
hours to solo sounds about average. 120 hour to solo not so much yes it's happened

Cool beans. Nothing but love for CFI folks. I refuse to respond in any snarky manner. I invite you guys to simtime for sim fun if you're ever in the PHX area.
Take care
