Thank you @mcfarhat. I'd be glad to explain things a bit further.

Firstly, the only allowed input into the ratio and percentage is numerical, so anything else will generate an "invalid" error. Any value entered that is not computationally possible also generates an error. So 110% and 0.5% will both generate errors. Entering a ratio that causes a value to exceed what is possible will generate an error that explains which vote value is too large. All errors appear as orange text just above the account name input box. Hopefully they are self explanatory and should a user encounter an error they should not need this detailed explanation to understand what to do to correct the error.

Second, let me explain in a little more detail how a whale benefits from SteemAX. Currently , whales have a couple of choices as to how they would like to earn a profit from their investment. One very obvious thing a whale can do is self upvote 10 times per day. Another method earns a return on a delegation. Yet a third way is to go for curation rewards. Of these methods, self upvoting is the most profitable. This is precisely why the Haejin / BernieSanders flag war started. But what if a whale could self upvote AND go for curation rewards simultaneously? But instead of self upvoting, if the whale created enough exchanges, and they made those exchanges at a 1:1 ratio, they would get the full value of the upvote returned to them PLUS the curation rewards from upvoting OTHER people's content. How awesome is that? :) If a whale creates ratios that are disproportional, say 1.1:1 or 10: 1 or whatever, then they may be losing out on the return of their upvote value, but they stand a better chance at receiving a larger portion of the curation, and if the content creator posts excellent, high earning posts, then the curation could potentially be much larger than the loss in returned vote value. A smart whale could use SteemAX to strategically target quality content creators thus increasing their curation rewards several fold. A bid bot, obviously, cannot target specific accounts.

Additionally, a whale can "spread out" their vote to many people by creating exchanges using a low percentage of their vote vale. At 1% voting value multiplied by 10 posts/day equals a potential 1000 upvotes per day.

I hope this helps to answer your questions. Thanks again @mcfarhet and I hope you're having a good day.

P.S. I sent you an invite to exchange upvotes with me on SteemAX.
