1. Sure, but luke was only born decades after mace's time
2. Both existing corridors and corridors that were there count as "the corridors of the jedi temple". Nothing about the quote hints at the exclusion of any corridors that fits the description.
3. Continuity is not retroactive. There's no relevant facts regarding revan to check against
4. "to have walked in" isn't dependent on tense. The statement can read, "jedi a and b are the most powerful jedi to have walked in the corridors in the temple". The use of "were" puts it in past tense. Anyone who has "walked in" the jedi temple's corridors are included in the quote. What pre sith version of revan it is doesn't matter, as all versions of revan post him walking in the temple "walked in" the jedi temple. "Ever" isn't needed for that. "Ever" makes it clear the quote applies to past jedi as well
5.The "were" means that mace and yoda "were" the two most powerful jedi ever to walk the temple. Just because they "were" the most powerful doesn't mean they still are the most powerful. All it means is that at a certain point, they were more powerful than anyone before who walked the temple. This will apply to past dudes because they chronologically came before yoda/mace. However this doesn't apply to dudes who came after because a new jedi surpassing mace or yoda doesn't contradict that they "were the most powerful".
6. You do realize the statement in the example you've posted is set in present tense?:
"the emperor's palace is the most prominent structure in coruscant" "and is perhaps the largest building ever constructed in the galaxy". Note how it says "is" instead of "were"
7. There are multiple statements that have retconned the part of the fact file you are isolating, but that in no way invalidates the statement being discussed unless you have something retconning it.
