Was told by a fellow DTV holder that as long as you leave the country after 6 months, the 6 months gets reset
the way i read it, was that it is 6 months out of a year we get on a DTV but he seemed to think it just renews as long as you leave the country even if you have already stayed 6 months
interested to see if this is the case, great result if so but not how I have read it
