I wouldn't be surprised either, but what we are talking about is RCS and the RCS is the same on the planes. Unless the customer changes it by adding a drag shoot for example
why do you have so much trouble? it seems it doesn't fit what you want it to be.
CM I tried to source your 2006 reference and came up with WIKI? based on what APA clown club said and corrected by ADF
In 2006, the F-35 was downgraded from "very low observable" to "low observable", a change
former RAAF flight test engineer Peter Goon likened to increasing the radar cross section from a marble to a beach ball.
[132] A Parliamentary Inquiry asked what was the re-categorization of the terminology in the United States such that the rating was changed from "very low observable" to "low observable". The Department of Defence said that the change in categorization by the U.S. was due to a revision in procedures for discussing stealth platforms in a public document. Decision to re-categorize in the public domain has now been reversed; subsequent publicly released material has categorized the JSF as very low observable (VLO).
