Thanks much for this useful video

Thx 4 the vid! It is also important to take into consideration the test altitude compensation factor: Multiply the reading you get with the factor based on the altitude.
Altitude (feet) Factor
500 0.987
1500 0.960
2500 0.933
3500 0.907
4500 0.880
5500 0.853

Pressing The Gas is necessary because you have to have the throttle body fully open, the only that opens the throttle body all the way is the gas pedal.

if you don't press the gas pedal all the way down during cranking you'll get very inaccurate results.

Anyone know why you have to press the gas in while cranking?

Thanks for making the video. I didn't know how to do a compression test before, but now I do!
