Cool! Did some E6 back in the nineties, what made it possible to keep that within 1/10th of a degree was to keep a towel in the tub & keep that on top inbetween agitations :-)
That stuff was super sensitive, also when it came to contamination…
Before that I got lots of single chemicals & mixed up old developers and so on, especially Kodak D-23 was great!
Oh and also D-76 mixed with a good weight from the base chemicals came out MUCH more original hahaha…
nostr:npub1apzt88v9pt9mzwa6rgsq2ujsle4nmml478kvjkm2n8wrttd0k63q6zfqk7 I like the towel idea!
It totally works for accuracy, almost all of the heat loss is stopped completely, or the opposite in your case I guess :-)
What I ended up with was to check the temperature maybe every third or fourth agitations, and then after a while getting the routine to keep it all at 1/10th of a degree Celsius.
As far as I could judge back then the E6 came out VERY well, better than some of the cheapest labs, later I used the best commercial lab & the result seemed the same :-)
These days E6 is done for in my case, but I do get some C41 done here locally, the commercial scans are actually very good and super cheap
