Default Developing temperatures

To elaborate, at 20c papers are normally developed to finality which means they are developed until they will not deepen the blacks any more. Ilford MG5 I have found needs 90 seconds to achieve this (MG4 was recommended that 60 seconds was enough) but I don't count down the seconds and whip the paper out once the time is up. A few seconds more won't hurt. The days of developer staining paper if you left it in too long have now largely disappeared.

If you develop in a solution which is too cool say less than 17c what you will find is the blacks are not really black at all - a sort of muddy grey would be the best description and the full black will never appear in a month of Sundays.
