Anyone else experience the pitfalls of the results generated on the calendar when selecting the "My Dates Are Flexible" button.

Over the past two weeks I have given up on this feature. If you are truly looking for your best pricing, you need to manually search around your flexible dates. The calendar will almost always display a result that is higher than the lowest available fare on those date. Conspiracy theorists will allege that this is intentional on UA's part. I believe this in attributable to inept IT.

EG...for example, try a one day search for BUR-LGA starting 9/21/2013. Click on any date in the calendar and the best available fare will show something entirely different. My results have been similar for other city pairs.
