Hopefully I’m understanding your issue correctly! Apologies otherwise.
You could add a time expression to the Evolution: e.g. “time*100” (but dont use the inverted commas!) the higher the number in the expression, the faster the evolution speed.
Thanks for the replies, no luck yet though. Since the Windows 10 update, my ColorVision profile seems to have been lost, as I get a message after start-up. I’ll need to borrow back the SpyderPro and re-calibrate, perhaps that’ll fix it!
