I've never used the 5 3/4 rule but I do used to run a string tight to the deck straight across the bottom of the rear trailing edge side fins and push the center fin up until it overlapped about 1/8" maybe a touch+
I've done so many I rarely use the string anymore...

There is some wiggle room with the bonzer 3 moving just loosens up, but the bonzer5 is Super sensitive.
That needs to be precise or you will suffer the consequences.

It's Best illustrated here in this pic by the fins, but especially by the shadows.
