IB Adaptive Algo?

[Dirk S 2]

Interactive Brokers users:

IB has been advertising (to me) their "IB Adaptive Algo". They claim that it can improve both speed and fill price. 

IB's marketing:

"Since you place marketable orders, you may want to try using Urgent Adaptive Algo orders instead, as they have better price improvement on average."

"Since you place non marketable orders, you may want to try using Patient Adaptive Algo orders instead, as they attempt to achieve the fastest fill at at the best all-in price."

So there is a setting for urgent and patient, depending on what you want to prioritize. I am a bit dubious because in fast moving markets this algo may miss out on entries. 

Has anyone any experience with this order algorithm?
