Something to consider I know
@gyngyn has brought up is some schools that say most recent is given the most weight actually only use the most recent for calculating their school average and in reality consider everything. I'm paraphrasing and hence might have missed something important but the general point is be a little careful with the vague phrasing like that. I have no knowledge of this gyngyn can comment as I know his school average's scores but it is something to consider. Goro's school also averages I believe.
