Lol ! I hear ya brother ! But , I can honestly say that all 16 race cars in our group on the Wallace calculator is dead nuts on……. Some of the guys have changed their car , either more motor, chassis work , which made the cars lighter! Punch the correct numbers in, it comes up correctly everytime ! Every car in our group runs motor , and alcohol and no smack ! Out of the 16 cars the fastest 660ft has run 5.36 , slowest 6.60 ! Out of the 16 cars there are 6 cars that run mid 5’s ! The reason I say all this is , most of the calculators the faster you go the more inaccurate they get ! But, Wallace is dead nuts for are group! I know it doesn’t really matter , but man it’s fun to sit around and bench race with the Wallace calculators !
