I detail a very clear step-by-step instruction manual on what you have to do to get your 100% upgrade.
It's worth $12.50 (someone else's $12.50, that is) to find out what a "100% upgrade" is.
Section Three: This section is where I give you 100% evidence so you KNOW that this loophole exists and works 100% of the time, guarenteed (sic)
This statement isn't, ahem, 100% true. It does not work 100% of the time. If there are no seats in F, there can't be any in X. Therefore, no upgrade.
