Of Averages & Addendums

[jmesser]

Would appreciate some advice on this.

Here's my situation: my first LSAT was mid 160s, second LSAT low 170s. When i took the first, I misbubbled on a section that I believe cost me a few points. Should I write an addendum, especially to the schools that average, explaining that situation and that I believe the second LSAT is more representative?

Love any thoughts anyone might have.
