Oooh, oooh, I know this one :-).  The reference angle is subtracted from
the main table so add 10 degrees to both the main table and the reference
angle.  You advanced all the timing 20 deg. with your change.  (If you
ever look in a Thrasher chip, Tom Chou added $2B to everything in the main
table (not counting the tuning changes), the WOT table which uses the same
reference angle, and the ref.  angle.)
