If you can feel your finger nail in the groove it is likely too deep

It's cheaper to buy new than even to re-chrome a cylinder

Where it matters is on the cylinder wall above the ports.  If there are marks at the bottom of the cylinder or on the piston skirt, you can replace the piston and get right back to work.
