Your X1 prediction is way too low, what do you expect to happen to the system?

Is not my prediction low, is your prediction too big.

30,000,000 is waaaaaaaaaaaaaay more realistic than 50,000,000, not even talk about 60,000,000...

I have a better question,n what DO YOU expect to the sistem? can you write your prediction Year on year?
