In pro tennis, where, say, a few topspin forehand cross-courts at a crucial time might make the difference between winning and losing, then 2% is an enormous number, or so it seems.

Am I wrong here? My understanding of the technical issues is far from perfect, so I have an open mind.

Check out pgs 132-133 of Technical Tennis - modern racquets can put four times, or 400 %, as much topspin on the ball, leading to much faster swings because the topspin will bring the ball down into the court. A ball that can be hit totally flat like an overhead on top of the net is where the 2% figure would come in.
