I think I see now -- you're claiming that scientists have to re-define decay rates because you think decay rates change.

I've got a lot of information to share with you as to why this is not the case. Should I start now, or would you like to present any information yourself first? All the two studies you linked to show is that decay rates are being defined with more precision. Maybe you can start by explaining how exactly you think decay rates changed in the past or are changing now. I'll warn you that you'll have to be prepared to deal with some science.
