Hi Roger,
 
I am working on plotting up the results of a blocking study.
 
Here are a few preliminary plots just to have a look.
If it doesn4t get too late I;ll send you definitive plots later this evening.
 
The plots show the cumulating z-score for all events calc4d using recipe 2 at different blockings.
Recipe is what you used for event 1. The blocking for that event was 15 minutes...
 
The end point of the plots is the final cumulative zscore. Each point is the sum of event zscores divided by Sqrt(n).
 
There are fewer than170 events because not all events are long enough to be blocked at the different sizes I've choosen. Events that don't have an integer number of blocks for a given size are kept but the final, incomplete block is dropped.
 
More later, along with some comments.
 
best,
 
Peter
