Is there a way to display a stat for the number of big blinds players have left in a tournament?

There isn't a built in stat for that yet (it is on the list to be added). There are a couple of possible workarounds but neither is ideal (both are pretty complicated and one only works for "hero").
This thread has a workaround for an "M" stat which works, but it does increase housekeeping times considerably. This post has the older version which only works for hero now.
