Super easy

Super simple color developing. I store my mixed dev and blix in accordion bottles and was able to successfully develop negatives 6 weeks after mixing. I have not tried to push it further than 6 weeks but I imagine you could if you did a snip test first to test the effectiveness if stored properly

Good chemistry, yet to have any complaints. Can't beat the amount of rolls you can dev with this thing for the price, practically $1.50 (please don't raise the price!). Only confusing part is that weird end run thing only gives you enough for the first batch. Am I supposed to be using it? What happens if I don't?

Let's say i developed 3 rolls a the same time using "35mm" with (Paterson Multi-Reel 3 Developing Tank) so this counts as i developed 3 rolls? so for the next time i'll add time as i used the developer 3 times? and also i count that i already used 3 rolls so i got about 21 rolls left for the chemicals sensitivity??
It is recommended that you add 20% replenishment of chemicals every time you put in new rolls of film

Does the liquid kit have the same temperature requirements for mixing as the powder kit? Or can you just yeet it and skeet it?
The temperature required to develop film with using the CineStill Film Cs41 C-41 Color Negative Film Liquid Developing Kit (to Make 32 oz) would be the same as when developing film using the CineStill Film Cs41 Powder Developing Kit for C-41 Color Film.
