THE GAME IS THICK

i ran my compression on my d16z6 again and it produced these #'s:
1st cyl. 165 psi, 2nd cyl. 160 psi, 3rd cyl. 162 psi, 4th cyl. 180 psi
-i removed the ecu fuse, removed all the plugs and cranked the engine 10 times and gave me these #'s.
my question is why is my 4th cylinder nearly 20 psi over 1,2, and 3?
do my numbers look healthy?
i also did a valve adjustment no more that 6,000 miles ago. any input would be greatly appreciated.
