1: "well then now san justo vehicle damage isnt as impressive if its less then 16 mph. They were thrown , smash then thrown then smash.... over and over ..."
Still, even though San Justo was moving at this slow of a speed the damage is very impressive nonetheless. It's also pretty hard to determine vehicle damage anyways, as we don't know if the vehicle was carried with the circulation for a long period, continuing to be smashed and dragged along the ground being destroyed more and more, or the vehicle was simply thrown a huge distance away from the tornado or was thrown at such a speed that its impact had such a force the vehicle was smashed apart. I believe that due to the severity of structural damage in San Justo, I think the majority of the vehicles were thrown with such force and at such high speeds that when they connected with another object they were smashed/ripped apart. Other vehicles however from San Justo u can see more traditional mangling, some images (to me), look similar to Moore 2013's vehicle destruction, and others more like Bridge Creek. To be honest, though, there are simply too many factors to consider when talking about vehicle damage for a really good claim to be made.
2: "but what is all this fast movement makes homes more badly damaged but slower isnt?"
I may have exaggerated this point in my post earlier, but, faster forward speed results in added speed in the core of the tornado, and if that tornado is already strong (like Smithville), the damage within the core of the tornado will be much worse compared to similar windspeeds at a slower forward speed. Which, if the tornado encountered a well-built home, for example, has 240mph winds, and is moving at 65mph, if the home was cored, then the damage would be more severe (not by much though), than if the tornado was moving at lets say 45mph.
3: "heck i think nws stated for Mayfield tornado speed (unsure how fast it was again) that structural damage isn't at its worst because it was moving too fast"
Yeah, I've seen this image before, Mayfield's average forward speed was 57.17mph, but I think this screenshot is taken a little out of context. First off, he says that the tornado damage would become worse, which is mostly true, contexual damage would become worse if Mayfield was a slower-moving tornado. I feel like the statement is pretty broad, and because so little detail is attached to it (like what type of damage is he referring to), this screenshot can be used to say many things, but what he said does not apply to structural damage.

4: "then there are tornadoes like hackleburg , smithville and the philadelphia EF5 that all likely had there EF5 damage made under 2 seconds and not the average 3 second gust so wouldn't at least these 3 and any fast moving EF5 that had a thin EF5 center damage path be more impressive?"
Well, yes, the damage in the center damage path will be more impressive with these 3 tornadoes, because faster movement speed results in a quicker windspeed within the core of the tornado. Take what I'm about to say with a grain of salt. Still, an argument can be made that the 3-second gust is just the measurement used to calculate the wind speeds of tornadoes when accessing the damage, and recorded windspeeds also use this format to make it less confusing / more efficient, but this could be entirely wrong however I'm not very versed on this topic.
5: "also its to note the most medium forward speed of a tornado is around 25-30 mph so that should be in the middle part of the moderate range"
Yes, moderate is the medium on my scale, I probably should have called it medium.
