Type XXI tactics

Has anybody written something like a tactical primer for the type XXI?
For now I have been trying to figure out an optimal snorting routine.
Initially I came to periscope depth at dusk, topped the battery, dived and spent the rest of the night at 4 knots, came up again before dawn, topped again, dived and spent the day at 2 knots. However this left me low on oxygen in the afternoon, so I added a third snorkel run to renew supply, but without staying up long enough for a full battery recharge. I also increased day speed to 3 knots. Any thoughts? Do people prefer shorter but more frequent snorkel runs?
