I have regulated a rebuilt Weber upright Duo-Art and it plays with
expression both pp and ff.  However, on the test roll for test #32 the
"Solo Power at 2, 5, 9, 12" does not increase successively as in test
#21 (accompaniment dynamics).  Please advise of any suggestions to
correct the situation.

The Duo-Art does a good job of expression as revealed on various rolls.
Does it need to have the "increase successively" to play effectively?
Thanks for anyone's advice.
