For me, time of year is more important. If you're in July, even the capped honey will be too wet to store. In October, the bees will have run out of nectar sources to finish the wax cappings. I rarely checked moisture content and judged by flow rate, if it's stringy, it's dry enough. In the late summer, early fall, I tried to get my honey pulled by state fair time in Ia. Another tell for honey harvest was first goldenrod bloom. These 2 tells usually would get the white honey before the dark, unpleasant, fall honey. Every locale will have a different harvest tell, if your a beek, learn your tells.
Checking for new supers, crack the top and look for new, white wax. If you see a bunch, drop a super. You always try to super with drawn comb, if you can't, pull a frame of honey into the new super and drop the foundation into the old super, do your work in the middle of the super.
About cracking the top, get rid of those stupid telescoping lids. You don't have any benefits except for another piece of equipment to maintain. Pro beeks use a sheet of marine grade plywood or signboard. For the price of one telescope, you can get 8 lids from a sheet of plywood.
Reading top bricks: A brick on edge, perpendicular, means an issue in the hive, undetermined, a brick on edge, parallel, means queenless. a brick on the flat side means everything is fine.
