The best way to tell how much is to fly the plane, go verticle at full power and hands off the rudder controls, if the plane pulls left you need more thrust to the right if it pulls right then you have too much, adjust it until it flys straight verticle without any input, the amount of thrust shown on plans is only a starting point that will get you close

BINGO!
If the plane pulls to the canopy, you need down thrust. If it pulls to the wheels, you need up thrust. You can spend forever setting the static thrust and, odds are, you're going to have to adjust it later.
