No, the problem is that we need to compute an initial value for everyone
who is currently a participant - this needs a lot of CPU time. If this is
not done, then everyone starts off at 0 as if they hadn't been working for
the past 3 years.

The computation only needs to be done once, and only for people who are
participants now, but it would be a big one.

People who join after this has been implemented will work automatically.

I think the computation could be done over a period of several days, with
a portion of the users being computed each day - I think the algebra of
this kind of average would mean that the results can just be added
together for a user, so there wouldn't be a need for flags to indicate if
they had been done yet. This should make transition a bit easier.
