About the P2 requirements. The required flight count for P2 has been going up, and I believe it is due to inequalities of training sites. One can choose to train at a glorified training hill (200-300′) and obtain a P2 just from flying there, so the requirements had to be raised for them. Some P2 pilots from elsewhere arrive at our lowest PG launch and find it high. 35 flights at our site has a lot more value than some other sites. I have been pointing this out to USHPA, but it remains a core problem.
About using the 750′ launch instead of Marshall for a new pilot. The 750′ launch is more demanding than Marshall launch, due to its flat-to-sloped shape, smaller area, terrain bump in front/right. For a new PG pilot, launching is the biggest challenge, so the 750′ does not help in this regard. Also, late afternoon the typical wind direction (more Westerly) further increases the challenge of using the 750′, which receives it as a cross-wind. The main advantages of the 750′ launch are: Quicker turn-around for increasing flight count and practicing landing approaches, usable earlier in the morning as Marshall often has an Easterly (cross-wind) breeze until about 4 hours after sunrise. No safety benefit to do unsupervised flights from the 750′, compared to Marshall.
