But that's a good thing that you found it.

The answer right now, is both yes and no.

When you are on the dual comparison page, it does NOT update the prediction at the top, nor the running prediction at that weight, and further down. That's bug #1. (This is the "no" part of the answer)

But, what you can do is create a "PermaLink" for your adjusted lineup. Once you swap out the wrestler that you don't think is starting, you can hit the "Create PermaLink for this lineup" button in green at the top right. But here's bug #2. Normally, when you click that create button, a textbox will appear right below the button containing the URL for that PermaLink you just created. Right now, that link is not displaying. BUT, it is getting created and can be accessed from here: https://www.wrestlestat.com/compare/perma/select

So, long story short, swap out your starters, click the "Create PermaLink" button at the top, then navigate to the page that I have linked in this message to see the updated Predictions for that dual comparison.

Sorry for the long-winded answer.
