<aside> I totally read those hidden bits. I am now 10th on the list for the book in my local library. Thankfully I have WoK to keep me busy! </aside>
See, that is what I thought - that when he was flying through the air and "righted" himself that it was a quick lashing to the ground which served to reorient himself.
And in both Kaladin and Dalinar's cases, the "glimpses" of being a KR, probably didn't start until they started living the ideals. For Kaladin, when he started trying to protect everyone who reminded him of Tien, and for Dalinar, when he started living the codes.
There is a thing, in marketing, where you look at what someone is doing (in marketing, buying X instead of buying Y) but in order to get their behavior to change, you have to (even without them realizing it) get the underlying thinking / unconcious reasoning for their behavior to change. It is the thinking that marketing can influence.
So, if you take that lens to it, you can see that by LIVING the ideals (e.g. the codes) Dalinar had to have started to believe in the codes. So, for his spren to give him little preview bits of the KR power, ESPECIALLY when they are doing things that are particularly attuned to the oaths, it is not unreasonable.
Of course, that just made me think of positive reinforcement training - it's like the Spren are rewarding people who live by their ideals with little snippets of power, and it just takes a Looooooooooong time for people to go all "oh, hey, I just did an honorable thing and got this odd outcome" (if they're not guided by Heralds, that is).
Am I rambling? I think I'm rambling now. Time to eat lunch.
