You got a great payout on this and it's well deserved as this is a detailed post explaining clearly how SFR works. I'm in two minds about bidbot use, although I don't use them myself. I haven't got round to joining SFR yet, but I probably will once I get myself organised. (Just got a text message from my tenant about a roof leak. This kind of stuff and being away on a course is distracting me from Steemit recently; non-stop interruptions!)
