Yes, I know I am overthinking some of this but for me better to underthink and screw up.

Thanks for all suggestions.
Negatory. Do not engage synchronizer until both motors are well up to speed or the master will be doing most of the pulling with the slave lagging. You want them both churning. I work the throttles up in sort of a wrist twisting motion. But that's just a personal thing. No reason to disengage sync slowing down; it'll come off plane straighter synced.
