Although slightly more tedious one can--- and probably should--- test papers for their fixing times in YOUR fixing brew of choice (inclusive of concentration), similar to film, as the clearing time X some factor like 2 or 3, depending upon the rejuvination and maintaince of the fixing bath. Overfixing increases the washing times but does not increase the archival perminance of the pictures--- and can via underwashing prove to reduce same. The key is to fix as short a time as need be, inclusive of sufficient room for error given the decline in the effectiveness of fixing baths and the dangers of underfixing, to reduce the demands on washing. This too can be tested for--- washing time for "fresh" fixing is the max. time you'll ever need as washing time will decrease over time.
- choose a fixing time that is sufficient for the most exhausted state of your fixer you shall be using + a factor for error. 3x the clearing time tends to be more than sufficient.
- choose a washing time to meet your targets for remaining hypo from a starting point of fixing using the time established above and fresh fixer.
Following the above procedures I think you will find that using concentrated fixer and a good washing procedure (dumping out the water a few times during the wash) times of 20 min shall prove sufficient.
