Stage 3 (Dry Season)

[Terranaut]

There would also be a huge variation in prey between those areas as well. To be honest , I think your doing narrow research on a vastly variable subject. You should narrow your experiment to studying what does well in captivity as oposed to attempting to simulate nature or if you do wish to try to mimic nature then choose one local and stick with it. You also mentioned measurements from other keepers enclosures? Do these people simulate dry season? If not shouldn't you not use their readings? If you wish to continue may I suggest choosing a sav heavy location and adjusting your husbandry to match the daily weather for that area. Seems the best choice to give validation to your theory. If the dry season is that important then your sav should live a long healthy life and that is the only true indicator here. IMHO
