Great job at sharing this tool with the wider community!
I make a small post using this tool every season. To be honest, for me personally it's not so much about how much I've earned, but more to see how well I've done across different rulesets and tournaments compared to last season, and with which card I've been using too much in stupid line-ups ;).
But it does do a very good job at summarizing your earnings, both in card burn value and in DEC!
