Can't believe it's been like 5 years since I started reading and participating in this thread.
Still haven't quite learned the method perfectly, but that is mostly because I haven't been practicing much.
I do feel a lot of improvement and I think that if I took only the safest bets (RBs and IRBs in the same direction as the dominant trend before the range break) I could be profitable. But I have another career to pursue, so no time to actually trade with money everyday.
However, I did find a great method to practice on weekends which I have just started. It's a software which allows me to replay forex data tick by tick and take paper trades.
This software is Sierra Chart which I thoroughly recommend. It has its own historical data which is OK for Bob's method. If you use this default data, you must set the number of ticks per bar to 130-160 instead of 70. I have found this number by comparing the number of candle bars on Bob's charts vs my own charts.
You can also set the price to increase on a pip by pip basis:

I am still using this soft in its trial version (free 15 days), but it seems really good and could really speed up the learning curve since you can accelerate the chart when things get slow. After this it costs 25 USD/month, I think, without the extra data feeds if you want a better one.
Hope this helps!
