I would say that this shim definitely helps you.
I just installed thiner shim (washer) in my K5 which solved front focus at manual focusing with the Katzeye split screen (I use KatzEye Plus Split Prism w/Microprism Collar). Now I have compliance between AF and manual focus.
My K5 was delivered (and my previous K7 as well) with 0.40mm washer. I ordered 5 washers between 0.15-0.35 and after some testing I installed 0.25mm one, which gave almost perfect result.
Split focusing screen has nothing to do with the micro AF adjustment.
K5 and K7 have identical part numbers of these washers :
77240.M02200A - 0.10mm
77240.M02200B - 0.15mm
77240.M02200C - 0.20mm
77240.M02200D - 0.25mm
77240.M02200E - 0.30mm
77240.M02200F - 0.35mm
77240.M02200G - 0.40mm
77240.M02200H - 0.45mm
77240.M02200I - 0.50mm
The price is $0.72 each.
