I've had a few, however they seem to resolve in fairly short order. At this point it isn't anything that raises flags for me, however I will keep a lookout for an increase in the "problem."

It is typical. And lots of forum entries for that.

Here's one of them:

Moonian,

Propose to collect data over a longer period and take snapshots at near 24:00 UTC and filter out duplicates to avoid double counts and sort by host, as when Inconclusives can loiter in the list up to 48 hours (the return time of the Reliable hosts is on average much less). The ratio to me over time seems to be in the range of 1:10, sometimes coming in bouts, where that probably is at the low end to maintain full confidence in devices WCG/Science team has no control over... all depends how much weight a single result carries within the groupings. If 1:5 is needed, than that's fine too. Still massively better than 1:1
