Yep, but it could also be confused with once for a lot of people I think.
Had a guy once tell me he could specifically hear the number one cylinder each time it fired because there was a miss and he thought the space in the sound meant the firing order was gone through and it was starting over (as in 18436572,,,18436572)
I had a heck of a time explaining that what he was hearing was 184365,2 (as in 7 wasn't firing) and that was the gap he was hearing.
How much patience does it take to explain that to someone without laughing at them or getting annoyed?:D
