This I think is very true.
I have been trying it out the last day or two, and haven't yet got a triple "in the wild" - I can when Fc-ing my other bases, though it took a few goes on each of them. At the moment, I am still getting as many 1 stars as twos with it (which is worse than with my regular strategy).
A few more days practice, I will probably be getting more triples with it than I have previously though (which isn't saying much). But it certainly takes practice - and precision. And for most players at my level, the cost of a tiny mistake is too high for the benefits.
