This is the same scenario as this but with weights applied to each number to account for their percent within the total population of occurences within the sample.

Our Criteria here: Win - a given team wins the game if they were losing/tied (in this order) in extra innings, 9th, 8th or 7th inning. Loss - a given team loses the game when they were winning/tied in extra innings, 9th, 8th, or 8th inning.
ZScore: is based on the population standard deviation and mean here. It tells you how many standard deviations from the mean you are. For wins, a positive ZScore is what you want as that relfects "you came back to win more than others". So 1.5 is better than 0.5. For the loss, a negative ZScore is what you want as that reflects "you did not lose your leads like others around the mean". So -1.5 is better than -0.5
"Which team in the NL West had the BEST improvement between the first half of the season and the second half of the season between 2013 and 2019 with late inning rallies and late inning losses.
From July to the end of regular season:
2nd half inn Rally wins: Rockies 0.66
Colorado still did not do good in the actual won/loss dept but they did improve on their late inning rally spread in the 2nd half of the season.
The figures based on this time frame (2013-2019)
