For peak sparging efficiency, yes. Lately, I've been mashing thinner (like 2 qt/lb mash thickness) and sparging less. I'm only losing around 3% in brewhouse efficiency this way, but the thinner mash is easier to work with.

You have to remember, these numbers aren't carved in stone anywhere. You can adjust up or down as you wish, and you'll still be in the right neighborhood. I personally don't like to mash with less than 1 qt/lb, because it makes the mash hard to stir and slow to drain -- but again, it's a question of preferences. A big part of the art of brewing is figuring out how the process works FOR YOU, and then tweaking it as you need to. Frankly, I'd rather have a consistent 75% brewhouse efficiency with less hassle.

This makes me think I can do this sooner that I thought. Amazing Site. Thanks.

Thanks JDS for articulating this. I feel like using more water in the mash has given me the results I prefer. Though, this is just a gut feeling, nothing I have observed empirically.

That is exactly what it's all about -- getting the results YOU want, not the results a book or a podcast host or another HBT poster says you should be getting. Brew what you like, how you like, and you'll always have good beer to drink.

I am new to all grain. It seems like topping off if you come up short is not an option in all grain like it is in extract. Is this right? What is the difference?

Also, if I run the amount of sparge water through my mash tun as recommended, the runnings become much more grassy and bitter after a while. Do I want to leave these out or just forget about that and add the correct amount pre-boil?

THanks.

You can certainly top of if you want or need to.

If I hit my efficiency at 5.5 gallons while I'm running off, I'll stop the sparge, let the rest of the mash drain and top off as needed. I've done it before the boil (with boiling water, to help it going) and I've done it after the boil with bottled water (to help with cooling.)

It could effect hop utilization with a more concentrated boil, but for most beers I think it has little to no effect.

I was reading this thread and noticed that the question about why a 10 gallon tun will drop more in temperature when grain is added than a 10 gallon tun.

I have to ask, is anyone considering the starting temperature of the grain?

Here is an even wilder idea... if you wanted your post-drop Tun temperature to remain the same, would it make sense to pre-heat your grain to say, 150 degrees in your oven?

Thinner mash/less sparge will also lead to less PH issues for those of you with hard water.

If you've got hard water, theres a good chance that by the first sparge you've exhausted the buffering capacity of the grain, so minimizing the amount of sparge water can be a good thing.

Always. I use Promash to calc my temps, and there is a field for grain temp in the mash screen.
