Guessing that on days that TROS is supposed to drop, it will have normal drops, while on days it is supposed to bump or hold flat, it will underperform (sort of like we saw with EG earlier this year). From 20 Sun (it will be -7 TLJ), could be:
Mon: 15.4 (-12 from TLJ)
Tues: 13.2 (-14.5 from TLJ)
Wed: 17.4 (-4.4 from TLJ)
Thurs: 9.0 (-10.5 from TLJ)
Fri: 10.6 (-8.4 from TLJ)
Sat: 12.9 (-7 from TLJ)
Sun: 7.6 (-6 from TLJ)
Mon: 2.1 (-12.2 from TLJ)
Tues: 3.0 (-4.9 from TLJ)
Wed: 1.8 (-3.2 from TLJ)
Thurs: 1.6 (-2.7 from TLJ)
Fri: 2.9 (-3.6 from TLJ)
Sat: 5 (-5.4 from TLJ)
Sun: 3.2 (-3.6 from TLJ)
At that point it would be -105.4 from TLJ's running total and likely to lose more as it kept going.
