Words with Friends - Winning Streak

I would like to say I am that good at Words with Friends but that would be lying, I won the first game (last in the screenshot) by only 4 points & the next by only 13 points.

I done well on the third game by beating Becky 466 points to 280 & the next game was a similar margin of 445 vs 233.

The recent game completed I won 384 to 285, it's Becky's turn to start the next game & my winning streak has got to end at some point?
