It's only a small difference but a crucial one the EF assist work's better in the old version interface as you can put a manual input time and it stay's there between the send and send page as the menu side doesn't refresh when you send and bring up the send page. But the new beta version the menu side refreshes so does the EF assist function so you have to continully input your time on the new beta version interface.

Yes I don't mind sharing the info. As I suggest for better value for money out of the function of Escapeflight Assistant that you use the old classic interface. As it seems to work better plus faster for ef'ing from all your planets when using the manual input.
