Additional insights relative to McCready theory:
…with a few newcomers painting thermals on course
for themEarly bird, doesn’t catch the worm……but potentially gets to complete the G-Cup twice in a day!
High Interthermal speed is not sufficient for success…Rush, ΔΣ (=Delta Echo)!
Too much of a good thing…is a bad thing…
…especially when easy does it!
