How can this practically impossible target be justified?

Suppose we are playing a 50-overs-per-side game where only 10 overs per side are needed for the match to count. Team 1 sends in pinch-hitters and gets off to a wonderful start making 100 for no wicket after 10 overs. There is then a prolonged stoppage and when play can resume Team 1's innings is closed and there is only just time for Team 2 to face the minimum 10 overs. The D-L calculation (Standard Edition) gives Team 2's target as 151 in 10 overs.
