Good catch. Here's a much worse case, using a real charset:
for i in 5-6 1-3 4 7; do ../run/john -stdout -inc:digits -min-len=5 -max-len=5 -node=$i/7 >/dev/null ; done
Node numbers 5-6 of 7
44563p 0:00:00:00 DONE (2013-04-29 21:25) 405118p/s 97443
Node numbers 1-3 of 7
47737p 0:00:00:00 DONE (2013-04-29 21:25) 433972p/s 68716
Node number 4 of 7
1p 0:00:00:00 DONE (2013-04-29 21:25) 9.090p/s 12345 <--- ouch!
Node number 7 of 7
7699p 0:00:00:00 DONE (2013-04-29 21:25) 69990p/s 58064
Ideally, 5-6 should be 31700, 1-3 should be 47600 and the rest should be 15872.
