Bro, I actually read that article before. But the thing is, as he mnetioned clearly, this chart is without taking into account ultra-modern RAM coating ( Except for the inner surface of the inlet duct, even though it was only mnZn RAM ) that F-35 has on its fuselage.
I mean it is no secret US was working on RAM coating for 4 decade now and they are ahead of everybody by far in this regard.
And F-35s RAM coating is optimized against S and X Band.
He also said,
"keep in mind though the actual RAM used on stealth aircraft may have absorbing rating of-15 to -25 dB depend on the actual frequency"
And i am gonna say this is actually a conservative estimate given how far US advanced in the field of RAM development.
And if we take cutting age RAM into consideration. Let's say it reduced the F-35s frontal RCS by -20dB against S Band.
And this is f-35s frontal RCS against S Band without RAM.

- S-band result of clean F-35 in Case 2 (-20° to +20° horizontal arc, -20° to +20° vertical arc)
So, now on top of that with RAM reducing -20dB....well, you can do the math on your own.
There are saying of USAF generals were they claimed, F-35 is the most stealthy jet in US inventory.
Note, please don't misunderstand the purpose of this post. I am not on a campaign to discredit ERIS's capability.
It is an excellent radar with cutting age GaN based dual axis AESA technology.
