also, it doesn't increase the odds in the same way as other games; instead of pure odds, each method adds up to 15 tops RNG rolls (maxed-out combio, max lure and shiny charm) which gives each wild pokemon that spawns 15 1/4096 chances to be shiny. it still increases the odds in almost the same way, but the mechanics are quite different. this one's not really a critiscism, just a titbit.
