Hey, everyone seems to be shipping for the windspren=shardplate thing, and I do not say it may not be, but I thought worth mentioning that there was a chapter back in WoR where Kaladin, Lopen, Rock and some other experimented with Kal's powers and when he stuck a rock to the chasm wall they mentioned there were spren inbetween, can't remember which kind.
Soo, I'm just saying that maybe windbreaking was something similar and that's why there where spren involved.
Similarities, both time adhesion was involved
Differences, first time Kal infused a rock, second time seem to have infused spren directly
