Did I hear it wrong or did the size of the band drop from 423(?) to 360 in just one week?

I thought I heard Brewer state that the size of the band was around 420 at the Lamar game. Was there that much attrition in one week or was the band only that size simply for the home opener?

I remember while I was there, we marched as many as 387 and as few as 338.
