Anyone have some insight on when the best time to buy tickets now is, and how to estimate fees?

It looks like there are four points per cycle on the oscillating ticket price graph: 40, 80, 120, and 80 DCR, approximately. I've heard that fees go insane when ticket price hits that low point around 40ish, but I'm not seeing any fee info on dcrstats or in wallet with getstakeinfo command or whatever.

Any advice or suggestions appreciated...
