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

I said above, the numbers I used where based on known high population density areas - the limits of the adjustments I made, where based on readings on captives (for eg minimum low temp in substrate burrows, max basking temp, burrow humidity etc etc), to ensure that the Sav had access to a safe environment (ie one that it was known to tolerate in the wild), at all times
Yes diet is another important factor, and difficult to judge, what we do know about the food chain, is that during dry season plants die off, this reduces the insect population, and the population of those animals which prey on said insects, and infact all the other animals in the area including grazers, scavengers and predetors are reduced in numbers, the chain follows all the way upto predators like Savs, which are very difficult to find above ground during dry season and must be dug up (Savs are an important food source for locals) - so we know that the type of food available to a Sav would be very diffrent to that available during rainy season - an interested party has offered to send me back some data when they visit Ghana this year, and food/animal types and availability is one area which would be interesting to look into

The SW desert of the US is significantly smaller than the range for Sav monitors. But despite the much smaller range, the countless pages of data were staggering. And to my knowledge, he is still working on that species (that was 1984, btw)
I say this to echo Terranaut. Regardless of your survey, regardless of your study group of one animal. Your conclusions/observations/whatever you are calling them are meaningless. It will simply further solidify in your mind that your way of husbandry is correct. Whether accurate or not. Your observational group is too small, your variables are not controlled and too numerous. Just enjoy your lizard. Make a comfortable home for him. Watch it grow and hopefully live a long, predator free life in the UK.

I am not trying to conduct a scientific experiment, I have said that at least a dozen times already.
I do not believe that ignoring 60% of an animals life cycle is a good thing, and until it is proven otherwise, my mind wont be changed on that point
