There must be a few WUs getting lost out there. You know how each unit is
sent out with a _0, _1 and a _2 suffix so that each unit is calculated three
times and cross-checked? Recently I've noticed a few _3's and _4's and today
I got a _5. Obviously a few results are being lost or not returned. My
understanding is that, if all three 'units' haven't been returned by the
expiry date they send out however many other copies are needed to get the
three results. A _5 must mean that all of the original three units were
lost.

Just thought I'd mention it. Anyone seen one higher than _5? Just curious.
