My guess is it may have something to do with room counts. Regardless of what room count you used to compare 2018 and 2019, you would necessarily get results close to each other as long as you used the same counts even if they were incorrect, because nothing changed on the
point charts between those two years, e.g., if you assumed 250 savanna view rooms in one year and 250 the other, the results would be the same except for any minor change due to weekend nights in any given season. An issue that still exists at AKV is exactly how many standard view rooms versus savanna rooms there are as a result of the major change done in 2012 when
DVC reclassified a lot of savanna view rooms as standard view at both Jambo and Kidani, which itself resulted in many point per night changes. It has been established that the number of standards at Jambo likely doubled with that change, but at Kidani it is still uncertain how many rooms switched
