Here's an updated Noki 1 cycle table. The cutoff for fastest human-viable bomb landing of 24.51 appears to be ledge grabbing at 21.87. Each additional frame delayed after 21.87 results in a frame delayed in bomb landing.
TAS bomb (Fast 1st Cycle) lands 1.667s earlier than 1st Cycle.
The fastest known N1 ledge grab achieved by humans is 21.11. You have to be 3.06s faster than than this and ledge grab at roughly 18.05s or earlier to save 1.667s over the current fastest cycle achieved by humans.
