The girl's 60 is one event that has seen considerable improvement over the past year, so it's the next event we'll take a look at...
What's insanely impressive if that despite only being (nearly) three weeks into 2019, the majority of this list has already surpassed their 2018 times, and we still have over a month remaining in the indoor season.
Maya Provencal currently tops the state with her 7.61, which is a quarter of a second faster than her 2018 PR. A quarter of a second improvement is quite a bit when you've only got 60 meters of which to do it in. Additionally, Anna Hall shares the quarter-of-a-second improvement.
What's all the more impressive is that within the top 10, Provencal and Hall lead with their .25 improvement, proving that cutting that much time off is very, very rare.
The biggest improvement on this list comes with a bit of an asterisk, because it's distance-star Taylor James, who has run over half a second better than her 2018 best.
What can't James do?
The average margin of improvement this season has been .09 seconds - so far.
With over a month remaining in the season, these numbers beg the question: how much more can everyone improve?
