I believe Ella is superior due to Height. I do not know for certain if this is the case, but I've found low shots to be fast, and several years ago,
I advised a speedrunner to use Ella with fairly major effect. Neil gets better Drive, but Height increases pretty badly after a few levels, and then that ball stays in the air too long.
In any case, my
Ella test run should give a pretty good idea what to expect. You can see I routinely try to keep my shots real low.
As for how I do things...
Getting the ball toward the hole was mostly me just trying some shots and hoping it got in. I will say that I had a script tell me the distance between ball and pin (
I did not include height in the distance calculation, for reasons I hope don't need to be said). Finding out how close I was in the trajectory is really helpful in understanding how I should aim, and pretty vital for flag shots.
I was never able to directly land the ball into the hole, only roll it in or flag shot it in. In fact, I have seen some pretty compelling evidence that it can't land directly in the hole, including the fact I've seen the ball bounce a few times on the top of the hole before being allowed to sink in.
Affecting the +/- power randomness, or RNG manipulation, is done in a few ways:
* Waiting a few more frames on the title screen
* Watching confetti fall for another few frames after getting an Eagle or better
* Waiting for birds to chirp in sunny conditions in some tourneys
* Waiting a few frames in rainy conditions
* Switch between viewing the Green and the rest of the course
And it does affect the +/- power adjustment. It'll also affect the weather, calling in or banishing rain, as well as affect winds.
The +1% power doesn't actually do anything, but -1% power can. When you get a maximum hit off the Tee, that's 100 power. +1% can't move that to 101, you just stay at 100. -1% would drop that to 99, though. With less than 100 power, the 1% rounds down to 0, and it basically doesn't matter. Higher percentages in rougher terrain definitely has an impact.
These are things I can remember right away. I can collect my notes and try to get more information from my old attempts.
