Stand development at 25C

I'd rather try to get all bathes on one temp than just trying to keep the developer at 20°C
I think the film suffers more from sudden changes in temp than slight drifting while standing in low concentrated developer.
I keep some 5 liter plastic jugs with tap and demineralized water standing at room temp that help me to maintain temperature thru the whole process.
I also rather transform temperature in duration with normal developer concentrations than trying to measure flowing water on the tap.
 
I did a run today without any kind of cooling just to experiment. These pictures are mostly of places I visit frequently so I don't care if the photos are ruined.
 
I just turned my faucet on cold (as far right as I could get it) and filled up my beaker to where it needed to be and added Rodinal at 1+100 and inverted for the first 30 seconds and then let it sit and inverted twice every 30min. Total time it sat was for 75min. Not the most scientific way to do it but from my understanding the temp doesn't matter *as much* because it's happening over such a long period of time.

Bear in mind that stand development, and especially with Rodinal, is recommended under 19 degC to keep the grain as low possible.

I notice more grain that I'd expect from a 100 speed film (based on other peoples' examples online) in the above photographs. But then again I'm lazy. I do want to try just putting it in an ice bath the whole time and see if I notice the difference in grain.
 
Do not make it too cold or you'll arrest the development almost completely. 17 to 19 is enough. Do not freeze it to death :)

Not sure - I have to track that in the future but I have no grain problem with the combo per se .. it's only happening when I under or over expose too much or just overrate a film in rodinal 1+100 like this
shanghai GP3 at ISO 400 - still I find the grain acceptable and I'm certain that was warmer than 19°C

this was developed in summer with the same film but rated at 100:
