I checked the dynamic meta data of a LON-CAPA problem and found 0.91 in 
"Mean Tries" in the block "Recent Detailed Assessment Statistical Data".

I thought this value represents the arithmetic average of tries 
considering all students who submitted at least one time their answer to 
this problem. This would mean minimum of 1.00 for "Mean Tries".

So, how is it possible to have a value lower than 1?
