Decent advice.......

Way back when, I crewed to quite a few.
When "I competed", we had nonscoring events (for some.....the "little guys meets".....ran as a contest, but no points/rankings.......you did as a regional, peeps helped you figure it out.....way back in the film days.....).


In general to this thread......all the glider prep in the world will NOT substitute for stick time.
Today.......knowing your glide computer, etc., helps almost as much as glider prep.
Yes, trailer is ready to go, not too fussy.
Chat with any crew......(I used to crew for a modest pay).
Training of the nut behind the stick is usually undervalued.

Go have fun......if you end up at 1/2 way on the last day....decent......work your way up.
Buying the "latest and greatest" for ship or instruments does NOT substitute for stick time.

For me.....when I flew a lot with good stuff......I was likely middling at best......but I sometimes worked a former US team pilot on local flights.

Spending big bucks for 98% does NOT mean you will win.
Make sure what ya got is working correctly, then spend stick time.

My $0.02......
