And that doesn't do justice to the fitter if one isn't going to give the new fit a fair chance by riding enough times to see if that odd feeling is only just a odd feeling that you'll get use to. Or if it's a odd feeling that is causing issues.
Effects of proper or better fit tend be obvious fairly quickly, within a few rides of about an hour or longer.
As for being fair to the fitter, that in itself shouldn’t really be a burning issue.
