As for writer opinions, they mean literally nothing if not published in a comic story. I can imagine a lot of fanboys, haters and others who work for the "enemy" because DC or Marvel pays better than their fave company. Some writers are legitimate idiots who know nothing about the chars they write, one just has to look what Thanos has to endure. I can't see them as special people or gods at what they do, except if they create a greaat and memorable story, like Morrison.
There has never been a comic book ever published that has superman above CM or BA. They have always Been shown as equals with BA and CM having the advantage due to magic. If superman can increase his strength by dropping mental blocks or willing it, then arm wrestling CM to see who is stronger would be pointless for any writer. Every close loss for Superman would be due to mental blocks??? He couldn't get BA out of the city, why didn't he will himself stronger???? When flash was fighting Zoom, why didn't superman drop his mental blocks and help???? Why didn't he drop his mental blocks against that shadow moon??? Why didn't he drop them against prime????? Against HP doomsday, why didn't he drop his mental blocks instead of getting outside amps???? There are many characters as strong as or stronger than superman... But you will NEVER see in any comic book, narration, quotes, interviews, blogs, or anything saying that CM or BA is equal to superman UNTIL he wills or drop mental blocks to get stronger. Besides, superman himself said that he and CM are too close in strength to call. Now if you do the opposite and look for quotes, interviews, blogs and narrations that states that CM and BA is equal to superman or stronger characters... Guess what?? They are all over the place and in plenty of comics.
Lying? That's your opinion. Very well answer these two questions.... 1. When superman and CM were arm wrestling an was trying to win, why didn't he will himself stronger or drop mental blocks to win? 2. Why would superman state on panel that he and marvel were too close in strength to call as they stalemated ? ( CM does not have dynamic strength) heck, let's go for three.. 3. Why does every character with dynamic strength gets it mentioned in their bios except superman? Know what? One more.. 4. Why does superman only have dynamic strength on KMC and it the same fans claiming it?
Well, one writer actually came up with these questions to show that superman does not have dynamic strength. He also pointed out that you all are using isolated instances vs 60+ years of the character. But to end this.. he said that the DD, HP DD fight would prove my point. Tell you later when he fax me. Have a good day.
I will feed it to you slowly, so that you understand it.
If you follow Supermans history like for example me, from PC days till more or less 2000+ it's obvious that he can drop his mental blocks.
Dynamic strength is what might cause you troubles. Or your interpretation of it. With Hulk it's easy, he starts at let's say 100 strength and with rage it increases till 1000 or so. With Superman it's different, his limits are unknown but from his history (if all out and if the threat was big enough) his strength is as big as the story requires, even limitless if necessary.
But let's roll with the 1000. Using always 1000 strength would most likely kill most people, so he learned to control it or better subconsciously block it. He doesn't even know his limits, as seen in DCnU. So he is using 200 out of those 1000. The threat becomes bigger, the mental pressure higher, the stakes greater and he "cuts loose" maybe to 400 maybe to 500 but it's enough or not to overcome an enemy, he might not even be fully aware how much there is left in him. In OWAW and FC he accessed more then ever before, as much as he did regularly in the PC days, which was enough to one shot trans to skyfather level Probes. The sundip is another boost he can use, he can access more strength faster, it's also a nice psychological thing if you read OWAW and against an Universal threat it's also better to not take any risks.
So dynamic might be the wrong word for it but that he cuts loose and that his limits are not known is a simple fact.
Against CM in armwrestling he will use the 200, his regular self, and be impressed doing his best. There is no danger.
