the more I practise... the calmer I get. Any new situation can be stressful and overwhelming... do something 10,000 times, I suspect even the 'dimest' of us will perform just fine.
PRS is not a complicated game... it does demand a wide range of skills and techniques but once a shooter has the base skills well in hand, they just need to deal with a course of fire which tends not to be too silly nowadays.
Many shooters dont understand, there really is a limited range of 'stages'... call them different things or use different props, but when you break it down, same thing on repeat. Learn the core skills to overcome these standards, and I bet shooters will be very calm just before a stage.... and those at the top of this game, practise alot.
YMMV

PS - note how the hit percentages continue to climb with the top quartile of competitors. In the early days, anything over 70% was amazing... today, high 80 and into the 90% is pretty common. More time behind the rifle, higher scores
