The patent for this brew claims films can be pushed 3-4 stops, with good results.I checked my notes and Perfection XR-1 is similar to the two formulas given below which appeared in US Patent 4083722 assigned to William Alexander Annerman of Sun Valley, CA on Jan 17, 1977. [snip]
I checked my notes and Perfection XR-1 is similar to the two formulas given below which appeared in US Patent 4083722 assigned to William Alexander Annerman of Sun Valley, CA on Jan 17, 1977. The notes also say that XR-1 was the fourth developer marketed under this patent. So perhaps an earlier developer was supplied in tablet form. There should be instructions for other films on the web.

I think as well the examples are the actual working strength solutions, the concentrate would be 4 times the weights (for 1+3 dilution), If you diluted the the two examples 1+3 as they are you would have a very weak, slow acting, developers whereas the imes seem about right if they were used full strength.
