Okay, before I start, sorry if this is a unnecessary idea, but it's what i always use, never seen any macros or programs to do it, so here it is.
Press Screen shot key, then tap forwards and jump, while it recovers form lag, you will have the perfect jump, I set + as SS, Arrows to move, 0 (numbers on the right side) to do it, it is also can be a good way to record how many jumps it took to jump somewhere.
It helped me get to so many places, hope it helps
