You jump into your backswing in reaction to the ball. You don't do it in advance of the ball being played unless you are certain of your anticipation, but that is a common issue with all footwork. It is okay to recovery reset, if it gets you fast enough in rallies do it. I am just parroting what a coach I worked with told me, everyone has their own approach to these things. Recovery reset at best means that you are ending up in positions that don't let you continue the rally, whether you need to reset as part of your transitions is an open question. I am pointing out that resetting as a step is often too slow, but if it makes you play faster then use itThe problem with jumping straight into a backswing for the next ball is that against skilled players, they will have a look at your backswing and will give you a ball that's incompatible with the next shot.
For eg if you got to a FH backswing but the ball comes to the BH, or getting to a BH backswing but ball comes to the FH. Worse, there's also long/short variations (especially against combination pips players), and nasty feints.
The benefit of the recovery reset is so that you're ready for all incoming shots instead of anticipating the next shot.
But there is a school of thought that you simply force the opponent to give you a ball that's compatible with your next backswing (via your shot quality) and do a weaker shot (for eg a block etc) if it is outside your preparation. This would then be more about playing the percentages.
