1)Do as many as you can in close succession, developing muscle memory, confidence and time at the DZ learning from the right people will help.
2)Currency is key, especially when starting out, the more jumps you do early will help with developing experience, it matters a little later onless 200 / 300 jumps but is still really matters.
3) Be prepared to sit around alot waiting for the right weather and conditions. If you think mtb is expensive, welcome to skydiving, lol.
1500 jumps under my belt, I’m still new and don’t listen to anyone other than an instructor or other responsible person.
