Pros:
- No Nido/forest manips lost to IGT0
- Don't have to memorize IGT0 backups
- No "did I fuck up or was this IGT"

Cons:
- Lose 1.0 to 1.5s to saving/synchronizing
- Mental energy during reset-heavy part of game
- Have to update IGT tracker each run
- Very small chance to miss the window

Conclusion: Could go either way. It's definitely a percentage play, but the effect is minor, and the mental energy could be significant.

Good reason to use it: "I just want to get a decent time with good execution; I don't want to grind this category."
Bad reason to use it: "It's optimal, so it must be worth doing."
Good reason NOT to use it: "I have the patience to grind Boat Rival deaths for a good time, and I need to avoid wasting energy in the early game."
Bad reason NOT to use it: "It loses a second in the perfect scenario, so it's not worth doing in a speedrun."
