better to be slightly less tight than too tight. less tight on the cones will then be sorted out a bit by the tightness through the axle nuts when wheel is in fork/frame.
Too tight you can total the bearing surfaces or on cheaper hubs actually push the bearing races out of whack.
You might also find that you need to inject fresh grease into there after a week or so of riding as it sorts itself out in there. Then recheck cone tightness/ bearing play.
AFAIK what you aiming for is an axle that can be rotated without any gritty feeling, turns free enough though there will be a fair bit of resistance from the grease and should have a knatts whisker of play (almost unmeasurable, but can be just felt with the fingers).
