What if I cancel my next score?

I got 147 for September LSAT, and I cancelled it. For October I got 155, and I’m keeping it. I’m booked to take my third attempt which is in a week, but I’m worried that if I happen to end up with a lower mark and cancel it, it wouldn’t look good on my record. I’m thinking it would tell them that whatever the Nov cancelled mark is, it must be less than 155, and therefore it wouldn’t be good.

At this point I’m not sure if I want to take the risk.

Any advice is appreciated.
