Yet for some reason you choose to believe one of these data but not the other one.
And btw just to give you a simple economy lesson: creating a situation were producers inflation is vastly different than consumers inflation is actually quite easy and has been achieved many times. It's enough to introduce administrative control of consumer prices ar start subsidizing consumer prices. Actually Germany recently did just that by subsidizing train pasenger tickets to keep transportation costs low.
