Lots of stuff from track to track - tire type, air pressure from front to back, sled type etc etc, weight bar in or out to max lenght, or even less weights,
On the ol drag sled it was tighten the chain and stand on it from the get-go so the tire dirt got under the pan instead o pilin up in front of it.
On the good sleds with selfpower, n air suspension etc, we would let er out about 30' or so just over the convertor, then slam it hard, again to keep the dirt where we wanted it - under the pan
On a hard clay track never mind the sled type we were 7200 rpm right off the pin

There aint nuthin like havin all four tires layin rubber n smokin for most of the run - yup hard clay will do that, lol
Spec-taters love it.
Then there are the sand type tracks where ya can never actually get on it full tilt.
Have ya never seen a puller walkin up n down the track diggin his toe into the track before the run?
Yah cant decide how to make the run till you know the track.
The short answer is ya need to know what yur truck can do on a given track surface and drive it accordingly.
And the best piece of advice I can give you - if it starts serious bounce - get outa it and lose - that extra few inches aint worth the expense of broken parts.
There is always another day......
