Does the 42 psi recommended tire pressure seem high to anyone else?

From lower 30's on the OEM, which felt OK, ramped them up a bit to the high 30's/low 40's before their change out around mid 4K miles. I was hoping that the rear wheel fishtail and rear wheel/front wheel gravel slides, short but scary, would be relieved.

Changed to road 5's, at 42 each. Ride seems harsh, hitting marbles is very noticeable. No gravel yet, but I am going to lower pressure to mid 30's and see how that feels on these new tires.

I've always had to drop rear pressure on bikes 2-3 psi or else they feel "icy" on normal roadways. that puts both my zx14r and h2 sxse at 39. I'm 190lb and never have a 2nd rider though. Front has been 36 on the ZX and 38 on the h2

After 2,958 miles my rear tire is done. It's worn down to the wear bars and looks like a slick in the center. My next set I'm going to try to run a lower pressure. I have trouble trusting Kawasaki measurements when they put statements like "Weight of rider, baggage and accessories must not exceed 195 kg (231 lb). " in the owners manual.

I ran both my tires in the low 30's for the first 3.5K miles, rough estimate, and the center and side tread seemed great. Very few highway miles.

Went to low 40's, and that center tread left is less than 1K miles later. I liked the handling with the lower pressure, less road rock mabel skating feel. I don't recall if I got any better mileage with the higher pressure.
