Thank you once again, Jeremy! You’re always kind with me, thank you. Now the feedback seems to be working just fine! Thank you!! Regarging the timer issue, I get that setting the timer before is simplier and easier, but I’m afraid (even thoug the effect is the same), some reviwers could argue that I’d not be following the original design strictly, is there a way to come up with a matematical form for the last timer making it be 3500 minus rt minus D1?
