Can someone explain to me why when I reach 48 or 49% I start to get losing streaks that pull me back down to around 44%. I then manage to get back to 48% and the losing streaks start again. I have also noticed that when I get a new ship, the first 10 or so games are almost all winners and I may get to 60, 65% after 25 games, and then I'm dragged down to 44% and the cycle begins. I've attached an example from today. Thanks

I reached rank 1 today after playing about 6 hours altogether. I had to fight against 3 CVs. I won two, although 1 player clearly had no idea how to land torps.
