On Reserved Instances: this makes RI purchase decision sound binary based whether or not 100% usage. Even accepting the gross oversimplification of binary based on usage, the discount is enough that the headline breakeven utilization can start at ~60% for 1 year and ~40% for 3 year RIs and then drift up from there as you start realizing the assumptions hidden in the discount, e.g. 0% time value of money, no future price cuts, etc.

Also very small point, but new 24 month RIs do not exist. Only place to find an odd 2 year would be on the RI Marketplace, that is if AWS were actually motivated to have it function...
