Add "for small aircraft" after "sink rates you'll see given."

Don't forget that when you are making a steep turn, your vortices are not
sinking straight down. They are sinking perpindicular to your wings. I
would also guess, this IS just a guess though, that vortices sink at the
lower end of the range of sink rates you'll see given.
