Model dependences
The blue values are NEW with fc=0.15 again
Broad picture of model dependence is not quite the same..
No one overwhelming source, but a build up of lots of changes of ½ to 1 sigma.
Mc matters now~same as fc
Mb is ½ sigma
Different parametrizations are outside one sigma
Alpha_s is about one sigma
OLD plus 6 model errors
NEW plus 6 model errors-quite a bit smaller..the charm did make a big difference

NEW Q20=2 its really this isnt it-there is nothing like the size of effect

OLD humpy
NEW humpy- doesn’t look the same and it should?- trouble?
OLD humpyNEW humpy doesn’t look the same and it should?- trouble?
Humpy doesn’t look as different as it did.
NEW ZJ- again its different could the k-factors explain it?
OLD ZJ
OLD ZJNEW ZJ -again its different could the k-factors explain it?
But was never that large
OLD alphas=0.1156 NEW alphas=0.1156-different
OLD alphas=0.1156 NEW alphas=0.1156
NEW alphas=0.1196-different
OLD alphas=0.1196
Is within error bars..but always was within other model errors
NEW alphas=0.1196OLD alphas=0.1196
Fact is alphas was never large and still isnt
