bobbling hammers, again

[Kent Swafford]

Don't try to make this into a mystery, Wim. It isn't.

I read Ed's post rather differently than you. I'm not as nice as Ed, so 
I'll go ahead and suggest that he was gently telling you that on those 
3 notes you do not have  tails with the proper radius and/or backchecks 
that are properly angled; if you did, they would work properly.

This is a not an uncommon problem. You ask, "Why would one key/hammer 
work perfectly, and the next one, with all the same characteristics, 
not?" Obviously, they do not in reality have the same characteristics. 
Keep looking.
