Guard flag calculation is somewhat involved (due to several
get-out-jail promotions/bypasses), but the essential
part is weighted uptime in excess of the median uptime of guard
candidates, or 98% whichever is lower.  Presently the authorities
have it somewhere around 96% (they do not publish the value).
Your relay is at about 91% and will be back as a Guard in less
than five days when it will hit 97%.  The attached XLS shows
it roughly, left side today and right side as-of 3/26.  Uptime
data came from the "1_month" section of

Built this sheet for myself recently and simply stuffed in data
for your relay.  Enjoy.

P.S. If anyone spots flaws in the approach, please comment.
