Totally agree but in case the players are very young kids (true in my case as its my 9yr old who plays), its very difficult to make that judgement especially if they are still learning to control the ball well. I find RacquetTune helps well here to keep a track of how the tension is going down. Not the best method I guess but being pretty new to all this, it made the most sense to me.
