The initial check should use real lengths as with modulo a
new required length of eg. 52 would be considered smaller
than an old length of 48 (2 < 48).
To get the 'batches' count 'newlen' must be divided and not
taken modulo BATCH_SIZE. Otherwise '101', which would need a
3rd batch to reach 150, w
sprintf() already returns the length
