T-Max 400 4x5 Graphs

I use T-max RS developer at 68 degrees.  Most recommendations are to use this developer at 75 degrees.  For me 68 degrees is an easier temperature to maintain and I have not seen any major changes in the characteristic curve when changing from one temperature to the other.  I use T-Max RS diluted either 1:5 or 1:9.  This means 1 part developer concentrate to 5 or 9 parts water, so I do not follow the mixing instructions that come on the bottle.  When I first open the package I pour the entire contents of packet B into the bottle A, put the lid on and shake to mix well.  I will then measure the concentrate as I need it and keep the unused portion in the sealed bottle in my refrigerator.
