I don't trust myself not to make a mistake in adjusting C41 development times for developer exhaustion or push while also keeping track of temperature, agitation and all the other times. So I made a neat chart to look those times up and you can have it!
Here's a preview. If you like it, click the button below to get the PDF.
This chart is specific to CineStill CS41 chemistry. If you want to adapt it to another manufacturer's specifications (or if you have any feedback at all), message me on Twitter.
