In warband, 100 was only average ability. Now its a real achievement. I could understand the the leveling rate if it only went to 100, though I still think it would be too slow. However, perks are unlocked at level 275 and beyond, which was considered high proficiency in warband, and I cannot imagine ever getting anywhere near to that level.
They want you to make Warband numbers with 10x less the xp.
I have a very hard time believing you have riding 110 on day 40. Did you choose all the backrounds that gave you extra riding ability? Even then I doubt it.

I hope this link works. This is from day 50 now, but I've been above 100 for days now, and reachted that in various playthroughs as early as Day 38 and level 8-9. And yes I started with 3 riding and 3 archery, as well as 1 Trade, 2 in Tactics and 1 in Medicine. The rest I placed afterwards, maxing Archery first, then 1 in Riding and then 4 in Trade and again the last in Riding.
It is easily reachable I did not bother with quite a few engagements and have also spent two days waiting. I am pretty sure I would otherwise have been around 130. My Trade would have been 70ish, if I hadn't had that bug where reloading resets your trade margin. I really thought I had 40 in Polearms...

You will just have to believe me on the days, my chars all have the same name and I am always doing Khuzait so I am not going to prove anything more with screenshotting loading screens
In any case when engaging 6-8 Looters, I can still manage to get +2 Riding and +2 Archery per engagement. I doubt this would work as well with polearms, I think there I would only be 90, as Riding scales wonky. Like 40m headshots stationary on a horse will raise Riding more than Archery, so even with a slightly higher multi in Archery, Riding did overtake Archery in all playthroughs in the range of 60-70, so quite early.

Edit: This is a rather stat-optimized build that I follow since I grasped how the mechanics worked and figured that my prior focus as a jack-of-all-trades with focus points in scouting, charm and medicine was rather useless. However, even in my first playthrough, at Day 40 I was probably around 80 or so in both Archery and Riding, and that was also with an army of 20 dudes and having raised stats like tactic and steward to 35 and 50, so it is all in balance.
