The most important double fault came at the end of a gripping deciding set, after Edmund had saved a break point at 4-4. Fifth set, normally you can work things out and see the lines, the whole of that fifth set, the finish line seemed so far away. However, when the Georgian broke back in the fifth game it was to spark a collapse in Edmund that saw him lose the next seven games. Four of them came in the fourth game of the third, the last of which was saved with a surprise serve and volley tactic from the Georgian. The fifth set was trying just to get through it, basically.
