Hey @rickysu. Thanks for your comment. I'll be looking at @minnowbooster today. It'll be interesting to see where it fits!

For @randowhale (as for all steemians) the upvote value changes with the steem price and reward pool movements. As at now (Wednesday 10.30 GMT) with the @randowhale account upvote:

• The 1.6% upvote (the lowest level) is worth $0.80, so down a few cents since my study. But even with 25% curation it's still well above $0.50. I'd also say it's possible to capture the 25% with randowhale if you post at the right time (the fastest post to upvote time I found over the three days I looked at was 6 seconds!!)
• The 2.1% upvote (the second level) is worth $1.01, so a doubling of the $0.50 stake. 40% of people in the study above received this upvote percentage or one of the higher ones.
• The average return in the study was over 200%, moving up to 250% when randowhalebonus was running.

The aim of what I'm trying to do is to put these stats out there so that people can make an informed choice. Everyone will have their favourites (I don't. I'm impartial!). Some people don't approve of the upvote bot system at all. But at least with the stats people will have a better idea of what they're getting into.
