Guess you did not read the whole story......
it says 3 h of flight instruction with an instuctor, and they mention
OR 10 Training Flights with an instructor.....

Which I would say should be INCLUDING, since in good
Soaring conditions the 3 hrs could be done in one flight.
On the other hand, a good instructor would not let you solo until you
learnt good aproaches and landings, not to mention aero tow practice,
which might take up all of the 3 hrs.

Among other items, the 5 solo flights are for demonstrating, that you
actually learnt how to SOAR, meaning that you can stay up for a while!
Which was not required before....years back. Then you might be ready
for your 20 flights, which could be done in the pattern.(short) which
I would not recomend.

This is how I interpret 61.129 f

AND This would be for an applicant who is testpilot material.
You know yourself that different people have different talents and
learning curves.
