The best thing you are doing is paying attention. There are so many variables and the more you can do to control each of them, the better you will be.

I am sure the brew will be amazing. Send me a bottle!

I batch sparge, since I don't do this for a living. I've seen a slight decrease in efficiency, but my FG is 1.018 or higher.
I may be not leaching out tannins as much as if would do a fly and get to 1.010 or less.
Ichiban supposedely does this.
Make the best beer you can regardless of efficiency. Not much money involved when you're doing AG.

After 18 All Grains I finally went for a 54% - 58% to a 76+%.

I now used the 5.2 PH stabilizer, went from 60 to 90 min. mash time.
Bought a water filter and used my house hard water, instead of using bottle spring water (sill use some for lite pilsners).
Added grains to water instead of the other way.
Bought my own grain mill "Barley Crusher" and adjusted it to .032.
I batch sparge with a mash out and now use equal sparge rinses.
I use a Gott 10 gal cooler w/ Stainless Steel braid (home made)
I showed down my sparge time it usually takes 20 min to drain my first running.

I now boil for 70 to 80 minutes and make sure the hot break is completed before adding the hops and starting my regular 60 min boil.
Boil @8.25 gallons down to 7.5 before adding hops the drain off @ 5.5 gallons into carboy.

I can't point to any one thing but I'm slowly keep getting better efficiency numbers.

I highly recommend making only one change at a time when adjusting your system or process. That way you will know what does make a difference and by how much. In terms of slower batch sparging increasing efficiency it should to the extent you don't give your grain bed enough time to fully drain before adding the next sparge. The trade-off is in time vs a small amount of extra grain. As far as 5.2 affecting your efficiency it could if your mash pH is so far off the enzymes are working poorly. If you are checking your mash pH or for starch conversion you will know if you need to adjust your water. I have moderately hard water and only use it (and only at 0.25 the recommended amount) for very light lagers, everything else has enough dark grains to drive the pH down into an effective range for mashing.

Hey fellas,

Well the good corporal hit 70% with todays brew. So I increased it from my last brew of 66% to 70%. I'll be happy if I can maintain that 70% for my next brews for sure. Gunna look into all your suggestions for sure and I appreciate the support.

Thanks fellas,
Grimmy

Way to go. That is something to write home about.

Hurray for that! Neither do I. My in-laws live 200 yards down the road!

Also, are you checking for conversion? If you aren't getting full conversion, then a longer mash can do you some good. You are already getting full conversion, though, keep working on all the other great tips you received above.
