I'm a bit too lazy right now to read the page in order to confirm this, but I think we're lacking a bit of information on this one. We have seen him transporting himself in the blink of an eye so I'd assume that this time is rather the average amount of time it usually takes, a rumor or perhaps an amount that he had decided on (when transporting to closer islands he will use a weak hit and vice versa) and the fast transporting would only be available in short distances. Don't forget that 3 days to travel from Sabaody to outside of the Grand Line is really fast, so he probably sent most of the people to far away islands where 3 days is surely an amazing time.
