...that's exactly what he said. Might not have been crystal clear, but he said that.

Allow me to clear it up:

Trophy A (sometimes, as he said, marked on the results page as SWA): 3-Event Sweepstakes(M/C/SR) for HS Varsity

Trophy B (SWB): 2-Event Sweepstakes (C/SR) for HS Varsity, 3-Event Sweepstakes for JH/MS Varsity

Trophy C (SWC): 2-Event Sweepstakes for JH/MS Varsity, and HS-NV

Trophy D (SWD): 2-Event Sweepstakes for all other entries not mentioned above.

In addition:

HS-varsity Div. 1 in marching receives the B trophy at Region Marching Contest

JH/MS, and HS-NV (yes, there is one school that enters two bands at marching contest) Div. 1 in marching receives the C trophy

This allows for the band to get the next bigger trophy upon earning a 3-Event Sweepstakes.
