You are trying to compare a C.calyptratus/veiled chameleon with a C. africanus regarding reproduction...but veileds can produce several clutches a year and the africanus generally produces one. (You would do better to compare C. africanus to C. chamaeleo.)
Africanus........

Calyptratus.........

I have kept both C. calyptratus and C. chamaeleons for quite a few years...hatched both...raised both to adulthood.
With veileds, they can reach sexual maturity as early as 4 months of age and can actually produce a clutch at that age. They can lay clutches about every 120 days whether they are with a male or not. It takes about 30 days from the mating until the eggs are laid. They can also be slowed down on the frequency of reproduction and the size of the clutch by controlling their diet and to some degree the temperatures they are kept at.
I have seen veileds kept together in 1.1 pairs (1 male, 1 female) and one or both will almost always suffer from the stress it creates. However, C. chamaeleons can be kept together in pairs and it seems to be okay (possibly because they only breed once a year so there is less stress?)....don't know about C. africanus since I have not had enough experience with them.
Regarding using milk powder...I can't give you an answer since I've never tried it. What I posted in my previous post about the husbandry is the way I keep my chameleons and the veiled females live to be over 6 years old and the males even older. My C. chameleon females and males lived to be over 6 too...so I haven't changed what I do.
