M2 Macbook Air Battery Capacity Drop

Ok so I purchased a brand new m2 macbook air to for school on August 28th. It now has 17 cycles and 98% Battery Capacity, is this a reason to be alarmed? My brother has a M1 he’s had for about 8-9 months, and it’s 99% Capacity, with 68 cycles. Is there something iam doing wrong? I keep it above 20%, and below 80%. Should I be keeping in plugged in more often? I’m worried because this was a very expensive machine, and iam a student.

MacBook Air, macOS 14.1

B. How Often I Use my Mac:

I've had mine for less than a year and it is at 96%. Contacting Apple, they tell me that it makes send due to my expensive use of it. But, I switch between Macs every 2 months. So, if I were to use this Mac always, then it would probably we way down there. I do lots on
