Wolverine has once ran rings around havok (literally). Unless someone has some reaction feats for havok to suggest this is PIS Wolverine blitzes.
Wolverine's been shown to be able to blitz him twice. Once, like when you mentioned when he and Sabretooth were running circles around him. And another time in Enemy of the State when Logan was being chased by the X-Men and hid behind a tree and stabbed 2 soldiers. Emma warned thee rest of the group he was over there and Havok was a few meters from the tree and blasted the tree, but Wolverine managed to get out from behind it in that panel and in the very next he was up in Havok's face and slashed his torso and he was down for the rest of the fight while Logan took off again. Wolverine also made mention that he's always been afraid of Wolverine, and blah blah blah, too scared to shoot straight and always has been.
