Not quite,
MOA (minute of angle) a unit of angular measurement equal to 1/60th of 1 degree or 1.0473" per 100 yards of range
so 1/4 MOA is 1.0473/4=.262"
at 500 yards 1/4 MOA is .262" (1/4 moa)X5 (range in hundreds of yards)=1.31 so each 1/4 MOA click on the scope will move point of impact 1.31" at 500 yards
20"/1.31=15.2 or 15 clicks
So say your shooting 820 yards your scope adjustment will move POI .262x8.2=2.15" per click
