Jointer setup question

I decided to replace the knives in my relatively new-to-me Powermatic 54 (not A or HH; built ~2000), but I ran into a problem.

As I had received (and been operating) the jointer, the outfeed table was zeroed to the top of the knife arc; everything worked fine and the depth gauge was pretty darn close.

When I replaced the blades I read the manual carefully, and it stated that the top of the knives should be no more than 0.015 inches above the body of the cutter head. To achieve this while at the same time zeroing the top of the knives to the top of the outfeed table I had to lower the outfeed table. I didn’t measure the height of the original blades relative to the cutter body, but it appears that they were much higher than the specified 0.015 inch.

Everything works fine now, but the “zero” on the infeed table reads at about 3/64ths of an inch (the picture below is with the infeed table 1/64th below the outfeed table).

Should I have instead zeroed the infeed table to the cut depth scale, then zeroed the outfeed table to the infeed table, then set the knife height to match the top of the outfeed table? This would result in the cut depth gauge being correct, but would also result in the knives being set approximately 0.060 inch above the cutter head body – contrary to the clear instructions in the manual:

Any suggestions?
