Yes I don't think you got a good deal after curation. You might have lost a little on that but I don't think you lost 20%.
What is hard to calculate is what the rewards actually are. Every time I try to figure it out the SBD, Steem price fluctuates so much the numbers never match up.
Out of that 13.50 what do you think your actual return was? It always seems way off to me? Also many of the tools don't work properly so its a crapshoot to figure something out here.

Try using @smartmarket its is very nice. The only problem is they have such a great demand that many times you have to keep trying because they just return your SBD. Any way @therealwolf is a standup guy and I think he is trying to be fair unlike many of the others who don't even care. It has to be hell to keep up with it and make everyone happy.

But over all I wish we didn't need bots to get some recognition for our hard work here. I also wish there was a way to make things honest and fair.
But it seems the way of the world is the way of Steemit. The bankers have all the power and we have all the work.
