Categorisation of the cause is also 'dirty work' performend by an individual.

Not to mention using totally non representative samples of piston types and disregarding those types that do use significant de-rating to acheive the most impressive reliability.

Moreover right there in that proposal even the fraudulently derived statistics are qualifying at better than the criteria stated. Thus making the point that even with dubious derivation there is not the stated basis upon which to draw the conclusion.

It is a nonsense.

This is nothing but an extension of a trade war being fought by obstructive legislation. This will not do anyone anygood. This smacks of French non-free trade tactics - the backlash will hurt everybody. The French sell a lot of their product in the US and this is shortsighted 'cleaverness'.

If we carry on using irrelevant and erroneous stats we are kidding ourselves.

This is nonsense and must not be allowed to succeed.

Govt agencies have an obligation to be 'fair' and not allow these shabby vested interests to prevail.

We have witnessed a disgrace already with the R66 certification and now this. The US govt maybe be forced to retaliate and this will be lousy for everyone.

They used to burn whiches on the basis that they didn't drown, haven't we moved on?

Every fair minded person should be repulsed by this.

(previous bogus statistics used for legislation have already been discredited here: 10^-10 not true! Maybe we could use some science rather than tea leaves?)
Bubba, is that you?
