Histograms of the total time in seconds for each division.
## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
The Division System Exploration
As you can see below, all D1 and D2 groups have very similar means, medians and standard deviations. If you look at the density plots below you can also see that there is little differecne between the two divisions after accounting for the number of individuals in each division.

Missing Previous Race
Here are the results of missing the previous race. On average after missing one race it isnt a very big deal. Individuals who missed the previous race on average change about 1 more position than individuals who didnt miss the previous race.
| missedone | missednone |
|---|---|
| 8.406279 | 7.428597 |
Missing Previous Two Races
Here are the results of missing the previous two races. Individuals who missed the previous two races on average change about 5 more position than individuals who didnt miss the previous race two. To me this seems to be a more serious problem.
| missedtwo | missednone |
|---|---|
| 10.90444 | 6.634261 |
