I coded a tracker/calculator (what is the best way to describe it, anyone?) for the U1D2M2 method posted by thelaw (link:://:.rouletteforum.cc/index.php?topic=15750.0)
It also has the Last /Furthest/ Last & Furthest Dozens tracker and the stats for the outcomes.
The green bubble by each option shows the wins/loss ratio. 1 means even outcomes, <1 means greater losses than wins, >1 means greater wins than losses.
The U1D2M2 and Dozens/Columns screens also has bet suggestions.
The Results button opens up the menu to enter the hits, Clear button starts agan, and the Exclamation is a boss key to switch over to a game.
If you want to see the bankroll and wins/loss tally for each even chance bet, open the browser's code inspector.
This should run in:
Safari 6+ (Mac)
Chrome 30+ (Windows, Mac, Android, iOS, Linux, Chrome OS)
Firefox 24+ (Windows, Mac, Android, Linux, Firefox OS)
iOS 5+ Safari
Android 2.3+ Browser
Internet Explorer 10+ (Windows, Windows Phone)
Suggestions and criticism welcome. Please let me know if any mistakes are found.
