I'll do it again, but I did follow the procedure from the manual, except I raised the back of the deck by an additional 1/8". Hardly think this should have thrown the lift mechanism (pedal) off by that much. I did find that my deck was at least 1/4" lower than the actual setting on the pin. At 3.25" (H on the pin), I am supposed to be able to get a 3" block beneath the deck; I found that the deck was closer to 2.75" at this point. So my settings have been off by at least 1/4" lower...
