How many baby tigers per birth?
What is the mortality rate on those babies?
Is this definitely not just greater efforts to count tigers?
The reported numbers come to about 1/10 of a cub per tiger per year, or 1/5 of a cub per tigress assuming equal numbers. If two thirds of them are sexually mature, then 0.3 cubs/year each.
That's close enough to the upper bound that it seems implausible to me, but these numbers aren't reliable enough for strong conclusions.
1-6, usually 2,3. If unsuccessful (all cubs die) the female can give birth about twice a year. If successful (raised cubs live) the female gives birth every 2 to 2.5 years.

> 50% before two years, but the female reproduces faster if she loses her cubs compensating for some of the loss.

It would require about 60 successful litters per year.
No, its 520 babies after you subtract the dead during those three years. Its 520 more tigers total.
