No, we have not changed the minimum test file size yet.
This is probably just random measurement variation.

The only thing we have started testing over the last few days is:

We tried to unstick some of the lowest bandwidth relays (below 1000),
and our initial results are:
* most (15) of relays we tried are actually very slow, or down,
* some (3) relays that we tried went down before we could see if we had
  changed anything,
* 1 relay that we tried increased its bandwidth 10x, but we don't
  know if it was because of us, or something else.

We are trying on a larger set now. If we get better results, maybe we
will make it automatic. But these results indicate that most relays
that are measured slow are actually slow for tor clients.
(Which is what matters.)
