This Q has enough computation factors to satisfy the requirements of a PhD thesis. When you consider droplet size, wind resistance, height, expulsion velocity, tidal volume and probably a lot of other factors it becomes extremely complicated. Sure. we know the distance is more but probably not much more.
So…. I will reduce the problem to high school physics level and ignore wind resistance, I will also assume your expulsion velocity, R, is the same as everyone else and only consider the effect of height on the ballistic path of the droplets..
Use the basic equations D=RT and S= 0.5*a* T^2. R and a are constants, and S is the height your mouth is above ground. Solving for D we find it is directly proportional to the square root of S. That simplifies the computation significantly.
So, You will spew 1.1 times the distance of a person 80% of your height.
You will spew 1.4 times the distance of a person ½ your height.
