Holy chit…your running control strips.
I applaude you. I wish I had the equipment to run such a tight process.

I'm doing personal work and running in daylight tanks so maintaining exact temperatures is a tough one in my situation.

I do presoak for tempering the tanks and reals and then run 3:15 with a replenished 1 litre working solution of Flexicolor DevReplenisher.

I HAVE thought of getting some test strips just for the comedy factor to see what I'm getting but…
ahhh the famous but, those things are REAL expensive.
I should've snatched the box I saw on eprey awhile back but even those got bid rather high.
