Step back and look at the whole mirror. If you got the outer zones all the same then the inner ones are problaby further than you think.
If they are still good and you have TUE then you may want to do a small touchup polisher. I've got one guy in my mirror making class that seems to mess up badly when he uses a full sized pitch lap on his 4.2" mirror. I've been getting him to use a 3/4" diameter lap (for you, probably a 1" would be better) and doing polishing in only localized areas. When using such a polisher, remember that you need to check to make sure that the glass doesn't get grooves in it frequently. The way that this is done is by not polishing in the same place several times in a row but rather working around the area.
