I worked in a very large reference lab with the old VIP's, and the gold standard was 300 blocks, and the solutions had to be changed (rotated).  That standard would explain why you currently are changing every other day (about 300 blocks).  I will say this...when the processors weren't changed as scheduled (occasionally the ball got dropped) we immediately noticed marked difficulty with cutting, and had occasions when the staining was adversely affected as well.  We used a hydrometer to check the alcohols as we rotated them, and the amount of carry over surprised me.  Occassionally the 100% alcohol would be as low as 95% after the processing run.  Had we not changed the alcohols per our protocol, that 5% could be disasterous the next day.
  Good luck!
