R22 low side pressure at 70 degrees.

I have an R22 split system 88 psig suction pressure and 152 head pressure. 75 degrees outdoor temperature, indor temperature 80 degrees. suction line temp 70 degrees,discharge line temp77 degrees. i didnt check the compressors amp draw. air filter is clean and blower is working fine 7.4 amps. temperature coming out of the supply registers is 67 degrees.R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).On gauge, using the farthest outside scale. On the high side, it should be around 225 degrees and near 70 degrees on the low. Also, I'm curious as to what my r22 pressures should be.
