A couple months ago, I refilled two Canon BCI-6 cartridges using the German method. I covered the outlet ports on the bottoms of both of them with tape and left the air vents on the top uncovered. I then covered the refill hole on one of them and left the other one uncovered. I left them sitting in an upright position on a shelf.
After two months, the ink level in the cartridge with the covered refill hole has not gone down at all but the ink level in the cartridge with the uncovered refill hole has gone down about an eighth of an inch. This means there is a slight amount of evaporation through the refill hole if you don't cover it.
Also, if you do not cover the refill hole, you run the risk of providing an air path from the refill hole to the outlet port which can result in an ink flow problem.
So in my opinion, you should seal the German refill hole with tape after each refill.
