You can also use the leave system to maximize your time at home. Effectively you can get seven blocks of seven days leave (one day off is added to each six days of leave). Spread them throughout the year and you will have a block of four days off plus a seven day leave block (but not together) for seven months of the year. For the remaining five months you have only the block of days off. So traveling back to Europe regularly is doable, but not ideal. Hope that helps.
