A brief digression into a component of the game mechanics which I never look at: Reputation changes over time.
Thomas goes to Durenmar in 1214.1, and offers to do scribal grunt work, of the sort mocked by his tyro equals, and immediately gains Rep 1: Pencil Pusher.
He then spends another 15 seasons after that, continuing to gain reputation as a pencil pusher. He gains 1 xp for every "act" that contributes to his reputation. Should we count that as another 15 xp in that Rep? That only brings him to Rep 2 and change, which seems a bit small for 4 years of demeaning work in a well-networked covenant that has frequent guests.
Okay, at a quick glance, Thomas spent 6 seasons reading (assumed) Q15 books, 4 seasons making the 2 copies of his 50bp grimoire, and 1 year spent learning 25 levels of spells and 5 pts of In (I will avoid the standard tangent on spending XP on spells, except to say that this exercise really points it out in stark constrast). One of those Q15s is from scribe, though and another is Durenmar Lore, so those could easily be explained along the way . So let's say:
4 seasons reading, 4 seasons copying for his private gain = 8 seasons.
1 seasons scribing under the eyes of a Q15 tutor, and
another 7 seasons of general scribing (during which he picked up 15xp of Durenmar as exposure, and somehow managed to learn 25 spell levels and a bit about Intellego along the way fudge fudge fudge).
Tangent: Assuming his 25bp Magic Astrolabe was made by Norbert, it's pretty easy to deduce that this cost the covenant of Laguna Sententia a grand total of 8 pawns of vis + some hermetic alchemy vis extraction which is like free money for any lab rat, in exchange for Thomas spending 4 seasons of copying AND 4 seasons at Durenmar earning the right to copy. Works out to 1 pawn/season. You know what, maybe that's not such a tangent. Such a raw deal should certainly be some kind of multiplier.
Okay, so his first season there, he agrees to be supervised in his scribal duties, which ends up working out sort of great for him, cuz he basically gets a Scribe'ing tutor, but it makes his reputation. Rep 1, or 5xp.
Now, the 4 seasons spent reaping the rewards of his demeaning duties with book access, he's just sort of a background figure, so I could see that earning him 1xp/season = 4xp, current total 9xp.
The 4 seasons he spends copying the book earns him ridicule not just for buying a bridge in Brooklyn, but also because it takes him so gorram long. Of course, the joke is on them, because he only took so long so he could make a copy for himself too, but he still earns his bad rep. Call that 3xp/season? 21xp so far.
Now, the other 7 seasons should be at least 7 xp just for STILL being at Durenmar (yes, I'm not doing this in any kind of chronological order, but that's fine). 28xp.
He specializes in lab texts. 7 seasons * 240 spell levels/season, average spell requested is lvl 30, that's around 56 spells he copies out for other people. 1 xp per, we're up to 84 xp, that places him somewhere above the Rep 5 that I estimated originally.

On the other hand, now I've established exactly what his reputation is, which makes it all a bit more usable in game. "Oh! I've heard of you. I think you did one of our lab texts. Hey, I heard you spent like a decade at Durenmar getting paid a pawn/season to do inventory and sweep up after the real magi."
