Everybody is different .... some people are luckier than others. Lots of people get less than 12 pretty regularly while some lucky girls can get 3 weeks. Not me. I can often go a full 2 weeks, but most usually get in the 9-12 days range when I get a finger or two that starts to lift. And if I had been scrubbing fish tanks it would be closer to 9.I hardly ever get chips tho.
It looks like you are leaving a nice neat margin, so I can't think of any obvious reason why you'd get the same lifting at the cuticle side except that maybe you just have more left behind on those fingers that you're not fully getting off before your mani.
Thanks guys. When I do my fish tanks I wear gloves but because my hands are dipping in the water the gloves fill up so my hands are wet for at least 2 hours each time I do them. It's the exact same two nails again, the others are perfect. I think I'll ad a tiny bit of bonder just where those two lift and see how I go next time. I'm pleased to have gotten over week out of it to be honest what with housework and the fish tanks I have to clean once a week.
