Advice On Improving Win Rate

So, another tomato here, working to get better. I am looking for advice on how to improve my win rate. According to tomato.gg the following stats apply to my last 60 days in tier 6+ vehicles:

437 Battles, more than 58.35% of players

1128 Damage per game, better than 58.13% of players

1367 WN8 per game, better than 70.61% of players

1.21 Damage Ratio per game, better than 76.28% of players

1.20 Kill to Death Ratio per game, better than 71.86% of players

0.84 Frags per game, better than 72.67% of players

BUT:

45.77% Win Ratio, better than 26.55% of players.

I have been working harder at this than I have ever worked at a damn video game. Studying weak spots, learning terrain, trying to predict which enemy tanks will go where (I really suck at this), but nothing I have done so far, in spite of improving my WN8 over 100 points in the last 2000 battles, seems to make any improvement in my WIN RATIO.

I am not one of those people who really thinks WG cares who wins or loses so I am pretty sure that my failure to win more often is based on something I am doing wrong. So, anyone got any ideas or advice on how I might improve my win ratio?

PS. Yes, I know I suck and if I would just GET GUD all my problems would be solved. Those comments are unhelpful, thank you so much. Trying to have a serious conversation.

Thanks EVERYONE
