I have a similar set back dominator jet with trim, 2* back cut shoe and ride plate . Adding the droop increased performance

You have a short droop on there now.
I think you are in the ball park , with rpm and speed for a AA cut.
A/b cut will get you a few mph.
The bottom of the boat needs to be straight for bigger performance gains .
You can get a straight edge and check the last three feet of running surface .
If you have a gap . Then the haul has a hook which most boats have .
There are exceptions , gull wings , daytonas , tunnel hauls . But even those at times need bottom work.
