So I wrote a quick little plugin just to play around with some stuff with speedshots (I was inspired by RNC). What it does is when you are in the air and looking at the ground below you, it will draw circles on that ground. If you were to shoot that circle at that very moment, the rocket that you would launch would hit the ground at the exact same time you do. I combined this with a landing predictor (similar to that of SyncR), and what this basically means is if you shoot the landing predictor when the circles cross over it, you have a good chance of getting a speedshot.
Unfortunately it's not 100% because I'm still not sure how speedshots work in the game, but it is a decent start. I'm still working on changing some values to get the circles to draw in the right place. Also, it has a much harder time getting the circles correct when you are close to the ground and going fast then when you are going slower high up (like preparing for a sync speedshot).
This plugin doesn't work as well when you have ping (I would imagine, I haven't tested) - it was mostly intended as a small toy for listen servers. One thing that I found fun was binding something to "toggle host_timescale .1 1" (a slow mo bind) and trying to get harder speedshots.

The plugin has updater support.
