Exclamation A/C system overcharged?

My tenant has been complaining of the humidity inside the unit. I'm not a pro, but I do small things like replace the outside unit capacitor every year and check pressures/temperatures to make sure everything is ok. It's an R22 system with what I believe is a piston-actuated flow control system. I'm not 100% certain of this, but when I open up the air handler, I don't see a TXV. There was no bulb taped to the low pressure output, just an insulated object that had several tentacles soldered to the bottom of the evap coil at various points.

Here's what I measured while the unit was running:
Inside wet bulb: 73F, outside ambient: 86F, vapor side pressure 87psig (52F sat temp), temp of low side pipe: 57F.

If I'm not mistaken, I should be getting 24-26 degrees of superheat and I've got 5. This means the system is overcharged, correct?

Thanks in advance!
