Yeah, I fat-fingered the number and reused 18 instead of doing the 45 correct the first time. I've spoken with AM about it, and it changes the difference they showed in card earnings from ~18% to ~3%.
I'll have to check how Splex calculates the value and where those numbers come from ($6.2 in fees to AM feels higher than I'd expect). I was happy with how I calculated the numbers which was what I had stated from the start. I didn't want to change any of the calculations after specifying the experiment for exactly this reason: if I change it and the results change, it would look like I was favoring one bot over the other.
Regardless, I think the point stands that the two services are pretty much neck and neck.
And I find it a bit amusing both services are trying to spin the results here as a big win for them. The answer is, and I know things that aren't black-and-white are hard, but in this case it's the truth: the two services are really comparable and people should decide for themselves.
If there was like a 10%+ difference in net earnings, I'd happily endorse one service over the other. But there just isn't. And while 350+ is a really good sample size, 1-2% is certainly within the margin of error. I'm not worried about maybe missing out on $0.05/day if I choose the wrong service. At that point it comes down to other, smaller things like I mentioned at the bottom. In this case, I really like paying fewer fees, as I keep more SPS, which is the most important type of reward to me right now. So XBOT wins that regardless of whether it's netting 1% more or less than AM might be.
