Is it okay to use Delay Nodes frequently?

Is it fine to use them [delays] a lot in many aspects of the game? I’m concerned especially about the short (0.01s - 0.2s) ones. For example when I make my character dash, I’m disabling gravity for 0.2s to make it work exactly as I want it to be. But does this time stay consistent on different PCs? I mean when you’re laggings a lot, will it count those short periods properly?
I already learned the hard way, that there are huge differences between PIE and Standalone game. For example Jump Max Hold Time lower than about 0.03s doesn’t work on my Standalone game, but works perfectly on PIE. And I’m guessing it’s because PIE has much less things to load. So theoretically slow PC would behave differently as well.
