How does the power counter work?

does this mean that my battery will last longer as Apple guarantee the battery life of 300 charges

Hi,

I had a new Macbook bought last month, then found that the power counter stays at 6 times for quite a while. I didn't let the battery discharge too much, usually not less than 95%, but when the battery level approaches 93~95% the charging process will start,and then charge the battery to 100%, what's strange is that the power counter doesn't add up 1. I'm quite curious to find out why, and most importantly, does this mean that my battery will last longer as Apple guarantee the battery life of 300 charges (reflected by this power counter of 300).
