These are generally a bad idea, as savvy coaches pick up on them quite easily and know what you are doing. Just another tool in their kitbag to make your life hell.
If you have doubts on a 'reversible' call, go conference with your partner and ask if he can add any information. Then you can change your own call if you think its warranted.
On other calls, you just have to live with it, as Clint said in "Unforgiven." Do better next time.
On a pulled foot and so on, you can just ask your partner openly if he has something different....some umps here advocate (as the BU) asking the PU if the foot was pulled before making their initial call at 1B, for example.
