Same prefix, taken from the fraud detection rule

The module uses a gliding window of 60 seconds, in order to keep track 
of "calls per minute". When changing time intervals, hence putting new 
thresholds in place, the "calls per minute" will not reset. In other 
words, when switching intervals, the new "calls per minute" thresholds 
will initially work with calls placed during the last minute when the 
old thresholds were in place.

Currently there is no way of doing this.

It should be "seconds", I will fix the misleading example in the tutorial.
