On the contrary, I think 2.3¢/RDM makes a lot of sense. In fact, I saw the same rate drop you did and I snapped up several thousand for an award trip that would have cost $466 more if purchased with cash.
RNE, not scrying accelerator RDMs going below 2.0¢.
Got to look at it in aggregate. Assuming that they had the price right before at 2.1 cpm for most of last year and that they have significantly raised redemption rates, then a) either they had the prices wrong before, b) they're going to cut prices this year, or c) they're dumber than I thought.
