I think it is pretty unuseful to have 13 decimal places in the advanced performance charts using the web client. Two or even three can be useful, having a CPU usage metric of 75.28172635478192% is just not practical and i don't see an scenario where it would help
It would be nice to have that number of decimals reduced to 2 or 3.
