Adams once recommended a test for developing time. He exposed a series of step tablet images such that they centered the entire range of reproduced steps. Then he developed the images for various times until he found the time where the greatest number of steps was reproduced. That was the optimal developing time. With the papers of that era, this could be a critical test, since after a while fog and extra contrast appeared and the range decreased. With today's papers, that generally doesn't happen to any extent, and you more or less develop to completion. With Dektol, that happens in about a minute and a half; with other developers it may be different. It may also vary with the paper.
