Case in point, this morning the Lynx @ Storm line was released at 9.5, moved up to 11.5 over a 3 hour span, and then got beaten back down to 9.5 in 20 minutes... Great if you capitalized on the +11.5 (I did), but irrelevant if you missed it. One group's plays cancel out anothers...
Net impact = minimal.
