I believe that unless a medication is designed to be divided (IE pre scored) you can potentially get 100% of the medicine in one quarter of the pill and the other three portions could be just binder, especially off label generics made in India for domestic consumption.

Actually that link does not substantiate your claim which IMHO is complete nonsense. If that were possible, then some 20mg pills would have 200mg and some would have zero. In order for every pill to have 20mg, the mixture must be uniform.
My experience with Cipla tadalafil is from breaking them into pieces often as small as 1/10th pill or smaller, using a scale (see my earlier post) and I have never found any variation in dosage.
Please note that India is not China. Here is the Cipla quality assurance facility:
