#1. Mongoose never blitzed Thor in that instance because mongoose couldn't even land any hits while Thor could.
#2. Being rushed by a god who's speed is not ever referenced does not prove Thor lacks great superhuman speed. In fact, it proves nohing in regards to speed.
#3. In Thor's fight with Wolverine he was cut off mid sentence which means he never admitted Wolverine was faster than him. And you forget the part of the fight where Wolverine gets smacked and Thrown by Thor before receiving a bolt of lightning with Thor saying that he's done holding back.
#4. Silver has certainly used in his speed when he's fought Thor.
#5. Quoting someone who doesn't write Thor books does not erase what numerous other writers of Thor have done, including the guy who created Thor, Stan Lee.
#6. Masterson Thor was ignorant of Thor's powers despite having them. Even Thor realized that. Even so, looking at all of Masterson Thor's feats, he has displayed superhuman speed and perception more than opposite.
