I have been using 5 minute hot mud for on drywall repair jobs for a several years. On small cut outs left by electricians or plumbers and fixing water leaks. I found that most jobs can be finished in one visit. I do not tape unless it is a large job. After applying the hot mud I smooth he area with a blade and then top over the hot mud with normal joint compound. I then texture with five minute oil based texture and it is ready to paint. I have found that 5 minute hot mud is very strong and therefore I don't need to tape on the small jobs. I hve not had any problems or issues so far.
