10-Aug-2020: ThinkSkate

I've made some progress with learning how to output the raw analytical tables so I can share them here! (Source code is at the very bottom of the post; I'll track it via Git soon.)

From the data contained in the file Skate Metrics - Base Data.csv, I have summarized the trick data down to the table below. Note that this table sorts by which tricks I've landed the most to the least given all my attempts ("Hits to Attempts Ratio", or Times Landed divided by Num of Attempts).

At the time of posting, the data pertains to 4 days of data collection (I'm lagging on inputting all the hand-recorded data), which accounted for 88 trick attempts. (I'm not certain yet whether I will update the files (both of them, only one, or neither), so what you see below might look different than it does when I'm writing this post if both files diverge.)

Trick	Hits to Attempts Ratio	Times Landed	Num of Attempts
