Sparge Temperature for 2 Rinses?

This is a really interesting thread for me as my efficiency has been low and I believe the culprit to be using too much sparge water at once. I added just under 5 gallons and ended up with 1.030 - expected was 1.050ish. I am happy to see that the speed of the draining doesn't matter as I don't have a valve installed yet (possibly doing today with toilet braid.

I am using a 5 Gallon cylindrical cooler in a paint straining bag and I am using 10lb grain bills. I still had about 1.5 gallons of dead space so I want to increase my grain bill but I am worried that too much grain may hurt my conversion.

My next batch I am going to do a 2 or 3 step sparge after draining mash tun. Adding 1.83 gallons for each rinse. My question is how long do I let the sparge rest before draining?

99% of the time someone reports low efficiency it is because they are getting poorly milled grain. I've gotten poorly milled grain before and gotten 35% efficiency. After getting my own mill, I clock 75-80% every time using the same process.

I actually crush my own grain. IMO I think I crush it to what I seen on pictures here. I use a Corona Mill set to about the width of a credit card. Is this okay or should I run it through twice. I'm not sure but is it possible to crush grain too much?
