What do these two times tell you? I had assumed 3 of 5 meant the average of the best 3 times out of your last 5 solves, but apparently this isn't the case?
 
You do 5 solves, and eliminate your worst and best solves. Same for 10 of 12.

Eliminating the best takes away the possibility of getting extremely lucky times on average, but the worst has to be out to help balance the average.
 
By taking out the two outliers, you get a more accurate average, especially if you happen to get a pop or a lucky solve in competition - its a very nice compromise between raw average and median.

We call this "trimmed average" in stats.
