I sometimes adjust bridge length. I sometimes adjust from one type of bridge I use. I sometimes adjust my grip hand position on cue. I sometimes adjust how tight and how I hold the cue with grip.
But, I the one thing I do not "sometimes" adjust is stroke speed. I adjust that going by what I see and feel on "every" shot from experience from previous shots in drills, ghost races, matches against other players...etc..etc.
I think most all if not all of the above is why I agree with the hamb method.
When someone ask questions such as bridge length, grip position etc...etc...etc I start wondering just how many balls has this person really hit during "quality" time on a table?
I'm not trying to be short. I have ask such questions in the past before I actually made myself spend quality time on the table and stop just playing pool which is what I thought, at one time, was practice when in reality, it was one of the biggest things holding my game back.

That last sentence is pure gold.
