Answer is NO. I rather rely on feel and rpm/speed gauges because the conditions are always different as well.
If you most of the time run in flat water with same load then maybe a "default" setting could be useful but in my case I actually most of the time end up running with motors at full tilt down and play with trim tabs when needed to balance boat and then I may tilt up a bit and check gauges. For speed changes at same rpm. I also follow the mpg or gpm! number that does not vary much for small changes at a given rpm.
One note more, try to use as many functions as possible during every ride or often enough just to keep all working.
Beyond A Wake, I guesss the bigger Gradys don't do well with the bow raised on plane. On my 208, sister ship to the 335, well maybe great grand daughter, I run 4 bars up on the TT gauge, which lifts more hull out of the water resulting in better speed at lowere RPM. This is only in a fairly flat water condition. I do drop it down for occasional lumpy conditions up here in the centre of the universe.
Freedom, it took me a while to get comfortable with trim tabs. All the old hands here (Hi Magic Bill) told me to use them and ignore the indicator lights, etc. They were right. You use them enough and you will start to just feel how they are working.
My 335 is so heavy with full tanks, all of them aft of midship plus generator so it is sticking its nose up when getting going. On plane it is ok but rarely need for trimming motors up except in higher seas. Add a few people in the back and trim tabs are used to trim down....
anyway as said y'all learn to deal with it by feel and not by preset numbers.
Have fun
