Nice to integrate them but i've 2 suggestions :
- Move the 'MS' unit in the hover description
- Round up the value : decimal of millisecond is not very important ;)
with these 2 things you will be able to have the entire progress bar
- reversing the progess bar could be for me more consistent
400ms is not well as 300 but currently the bar for 400ms is more filled as 300
The logic for other value is opposite..more the bar filled, best it is
(sorry for this approximative english :)
