[Geysers] What is Grand's Shortest Interval?

[JEFFREY CROSS]

What is the shortest interval of Grand ever noted?

I have one candidate, as follows:

07 October 2012
Grand 1459
Grand 2001, I = 5 hours 2 minutes

The geysertimes record shows the second eruption occurring at 1959, which would make a 5 hour interval exactly.  However, I cannot reconcile the 2 minute difference between this time and my own observation, as I was passing Belgian Pool when Grand began.
