Just don't use the convert option unless you are an expert and know exactly what you are doing.

I agree and think this should be made clear in the interface. I just mentioned that to @TimCliff as well.

Currently, three of the top 20 witnesses are advertising a price bias, but yes, it seems it's not currently in place. If it was, people would probably be even more frustrated by the results of their conversion. Could that frustration be a good thing and force them to get educated about it next time? Maybe... but I'm doubtful. There's already a "loss" (at least perception-wise) going on right now, and many still don't understand what the convert function does.
