Honing a cylinder. How much?

[krypton]

Ive got one of those spring loaded, 3 leg hones. I seized a ring in my corsa and it left a tiny scratch that barely catches the very tip of my fingernail.
I have honed it for about 30 seconds at half speed on a regular drill. The scratch barely touches my fingernail. Should I keep honing this until it is out? Or how much can I hone? and should I still use the stock piston and rings (new). The motor didn't have 1000 miles on it hardly.

image, the one white looking mark toward the top above the port, is the one i can feel. The rest, im not sure about. I think maybe running it did that. Don't feel anything on them
