This is what I'd do for most British ales (maybe a 75 min mash for some). Never done an APA but I reckon that mash schedule would turn out just fine. Mash out for 20 mins (as per Coldspace) seems to help efficiency too.
Tried it myself on the weekend. Sprinkled water out using my fingers then mixed in. Repeated maybe ten times. I used nowhere near 100ml of water for a 4.75kg grain bill.
I've never seen so many properly cracked grains with almost fully intact husks.
It is definitely a useful technique.
Just finished reading it. Great book.
The amount of sugar used in some recipes is staggering.
Wondered which recipes were the favourites. Good to know which they are.

Big generalisations here;
Bottom fermenting yeast for lager at cooler temps compared to top fermenting for ale at warmer temps.
No yeast derived flavours for lagers, yeast derived flavours important in many ale styles.

Sodium met is an effective disinfectant. It is used in lower concentrations in wine (the dose maketh the poison) which is why it slows rather than kills the bacteria. The no-rinse, no-blowtorch-your-sinuses aspect is why it is not preferred to those you've mentioned.
