I've shot with Wert, and his anchor is the highest I've seen.
I shoot with a high anchor, cradling my cheekbone into my index finger. I also tilt my head slightly to bring my eye over the arrow which further lowers my point on. I usually end up with a point on from 23 yds (heavy arrow) to 40 yards (light arrow).
Right now tuning up a 42#@30" Imperial longbow shooting 510g Sitka Spruce shafts. Point on is looking to be around 25 yds. It is not a speed demon, however.
But i agree, the single best way to get a lower point on is to raise your anchor and shoot 3 under.
