This will be difficult to retime as nobody actually saw the final block exploding. I retimed it to the last TNT I saw exploding, if you want you can add a few seconds to until the last TNT is done exploding.

P.S. all blocks should be gone from chunk, but exploding TNT is an entity so should probably not be counted as a block IIRC. If i am wrong here, just add a few times the time TNT takes to explode. Better to just time to the last possible time. Stay Hydrated Seed: 923240697226366877

Other perspective: __Blacky:

Mod Note: Retimed RTA/IGT from 6:47.267 to 6:48.433. Retimed ending on first frame the entire chunk is visibly empty.
