First off, kudos to Enginerdz for the Season 3 chart, hes the inspiration.
I know we're 14 days in, I had trouble keeping up with the levels mainly due to, well, non World of Tanks things. I searched for a progression chart which served me well, but I couldn't find any or I just suck using the search feature on Reddit.Anyways, I figured you guys should get it as well, it contains the date, the day number and the level required.I understand the chart looks uggo, but I've always been bad with art.
To the mods: I put the flair as guide, It's my first ever OP on reddit.
Edit: Fixed the Level requirement calculation since the last day does not count. Kudos to u/Brunopunck49.
