I last mixed up a 5l batch of xtol 1 1/2 years ago and it only went "poof" a few weeks ago. No tears, as there was only 1/2 liter left. XTol is not the only dev I use, but an important one. But I can only use so much, so fast! Now, my usual one shot dilution was 1:2. This was my favorite for tonality, grain and sharpness. In an effort to actually "use" the whole batch before it goes boom, I am considering using 1:1 or stock. This is what brings me to my question. Replenishing requires a "top up" of about 70ml, which effectively gives me the same consumption of 1:1 (my drum only uses 150ml of dev / roll). Is there any advantage to replenish over just developing 1:1?
