I noticed your spreadsheet includes several skins that were "vaulted" during the Arcade event back in August. Many of these are near the top of your lists and unfortunately won't be going on sale in any predictable manner. This list includes (and in the order they appear in your categories):

975 RP

Queen Ashe, Obsidian Malphite, Imperial Lux, Sinful Succulence Morgana, Major Ziggs, Winged Hussar Xin Zhao, Jailbreak Graves, Rune Wars Renekton, Guerilla Tristana, Primal Udyr, Secret Agent Miss Fortune

750 RP

Defender Leona, Sun Goddess Karma, Fiddle Me Timbers, Explorer Ezreal

520 RP

Big Bad Warwick, Sheriff Caitlyn, Ruthless Pantheon, Vindicator Vayne, Prom Queen Annie

I'm linking the League News post and the Support site for references.

Many thanks for keeping the spreadsheet as I certainly use it for purchase planning.
