I wouldn't say it's the most accurate prediction method, but it does represent sort of how the company wants to move forward, at least in terms of parks they'd give lavish marketing budgets towards (and thus, the parks the company wants to build up). The parks without presidents that have been marketed since then are Dorney Park, Six Flags Discovery Kingdom, Six Flags New England and Six Flags Qiddiya (which each have only been featured in marketing once, or, a 2.4%).
