1984 Supra Rider Ballast Fun!

Boat is a 1984 Supra Rider (almost identical to a Sunsport) w/ Chevy 400 small block, 13x12.5 3-blade prop. Manually adjustable wake-plate.

Hey everybody! Finally got some good weather here the past few weeks so I've been getting out to the lake once in a while.
I've been adding a little more ballast each time I go out. (Mosly random stuff I find laying around. Hehehe!)
Last time I went out my impeller broke before I could get a set in so I didn't really get a chance to test-out what I'm running with. (Wake-plate is adjusted up about 1.5 inches from level.)

So far this is what I have:
Fixed weight:
I put 3 old cylinder heads under the center floor in the back. I'm guessing about 45# each. 3x45=135#
I have 5 75# sand bags in the very back corners (3 port and 2 starboard.) 5x75=375#
I found an old differential carrier with gears. LOL! About 30#. By the cylinder heads. 1x30= 30#
I also found an old lawn tractor weight and stuck that up under the bow on the port side. 1x40= 40#

So total fixed weight is about 580#. (165 center/aft, 150 starboard/aft, 225 port/aft, 40 port/bow)=580#

Water weight:
I bought some 6-gallon water jugs that fit under my rear seat (1 port and 1 starboard). 2x48= 96#
2 more 6-gallon jugs under the bow (1 port and 1 starboard). 2x48= 96#
I also rounded-up a couple 5-gallon buckets for in the back (1 port and 1 starboard). 2x40= 80#
I like to fill the cooler all the way full with about 10 gallons (center/bow) 1x80= 80#

(Currently 176# bow and 176# in the back) So far total water weight is about =350#

So right now I'm at about 950# total. (23% Front to 77% Rear, and 60% Port to 40% Starboard.)

For you guys who have weighted Sunsports and Riders, what kinds of ballast moves effect the wake in which ways?
From my understanding, you're supposed to put all the weight in the rear, then add to the front until the wake cleans-up at you desired riding speed. Is that right? Also what kinds of adjustments effect the "rampiness" of the wake?

I know there have been quite a few threads on this and that, but most of those are on the newer Supras. I noticed that most the newer v-drives use way more weight up-front. With my engine sitting right in the middle, I'm assuming there should be a large bias towards the rear. Would love some input please!
