Let's be quite clear.
Anyone who says "Aircraft X has an RCS of Y square meters" is by definition full of
because (1) RCS is dependent on wavelength and aspect and (2) if you know what the right numbers are, you know that you should not cite them.
Such quasi-random numbers
may be indicative, but that's all. And I'm sure that a number cited by a reporter for an Indian business news site, quoting an unidentified government official, is utterly reliable, or at least good enough for a fan trying to prove a point.
And Ken, you seem to be arguing in circles. You're trying to bolster one dodgy assertion (that inlet design tells you conclusively how stealthy an airplane is) with another (that RCS numbers culled from different corners of the intertubes are reliable).
