What people aren’t recognizing is that in SPG’s system a list is sent to the hotel each day with a “suggested order” for upgrades. This algorithm most surely considers Plat 25, Plat 50, Plat 75, Plat 100 plus many other factors (probably) including Lifetime Nights, Lifetime Spend, Lifetime Points, Years Elite etc. (the algorithm is proprietary). So while the FDC may not see your status on his/her screen it has been factored in to your suggested upgrade.
