Scaling up/down contracts on Kalshi and managing risk?

Hey everyone, still pretty new to the Kalshi space and finding it fascinating. I've been dabbling with small positions, mostly just to get a feel for how the probabilities move and what impact new information has. My question is around scaling: when you're confident in a read, do you typically just increase the number of contracts on the same entry, or do you look for new entry points on subsequent price dips/rallies? And how do you personally manage the risk of that increased size – is it just a hard stop, or do you have a maximum percentage of your account you're willing to commit to any single event, especially when scaling in? I'm trying to figure out a systematic approach to risk sizing beyond just throwing a flat amount at everything.
