I recently picked up the three armorsmithing techniques that allow for repair and I noticed that the roundtimes are pretty long (~15-20 seconds per step) when compared to the repair times for cloth/leather armor where I also have all three (7-10 seconds). Is this extra time intentional? I don't really mind if it is, I just want to make sure my Advanced Armor Repair technique is working correctly.

Also, and not directly related, the final repair tech is called 'Armor Maintainence' in the game when it should be 'Armor Maintenance'. File that under the being pedantic category of complaints if you please.

No my forging skill is quite a bit higher than my outfitting skill, which is garbage, but now that I think about it it might be because for leather/cloth armor repair I use some nice crafted tools (slickstone and needles) but for metal repair I use store bought wire brushes and oil. That's probably the reason.
