[Geysers] Old Faithful Dec 21-22 2016 - Consecutive Shorts

I certainly remember this formula -- using it, even -- but I forgot the  
values for "m" and "b" a long time ago. And it didn't turn up in a search  
through a few things. However, that formula was devised (I think by Rick  
Hutchinson or by one of Rick's "assistants") way back when Old Faithful's  
average was somewhere in the 70-minute range. Therfore, I've got to believe that  
the values for those constants have changed a great deal.

Years  ago, someone reported a formula of the form y = mx + b for 
predicting Old  Faithful.

Y is the interval
X is the duration

How has this  formula changed from one year to the next?

Specifically, are the  current values of m and b what they always were?  
Larger?   Smaller?
