I do like ttrr without milliseconds because it pushes you to perform out the boundaries, but if people like to count milliseconds then why not
In regards to pushing you to perform out the boundaries, isn't it pretty much the same either way? Milliseconds or full seconds, you are going to push yourself equally as hard either way no?
If I were to choose though, i'd expect TTRR without milliseconds to feel ever so slightly more relaxed against more experienced players as you have a 50 frame window to draw as opposed to a single frame.
On the other hand though, depending on a players perspective, perhaps it's the increased chance of a draw which pushes you to try harder to prevent more time being spent doing rematches. Although i'd still say the smaller possibility of a draw with milliseconds would mean the stakes are higher pushing you to get the best possible time.
Although from my perspective i'd always be playing against myself anyway, regardless how good or how bad my opponent is in anything, i'm always trying to push my own personal limits, i'd rather lose and play well than play terrible and win.
At least it's in agreement either way is suitable though, i'm happy either way just think MS is more accurate and realistic.
