Distributed platforms take longer to update counters by default. The old
7500 was really fun in how it handled counters between VIP and RSP. I've
always seen it around 15s, not 30, though. You will also see this on any
of the virtual chassis switches when referencing any interface that is
not the current master switch. The 6500 is uniform with all interfaces
(and roughly looked like 10s update with current code level).
