Just listing some improvements found since the TAS was submitted, for documentation:
1. In Fire & Water's second section, you can land on the zip line and then jump to an exposed corner of the oil tower. From here, simultaneously tap up on the control stick and jump with a certain rhythm and Bond will speedily climb the tower and be able to land on one of its arms just under the padlock and cut it, ending the level. This skips waiting for the elevator to come down and saves 20 seconds. Because this skips killing many enemies, it may rob the TASer of the gold reward (I haven't tested). To prevent this, the TASer might have to make a little time sacrifice in section one to kill more enemies.

2. In Forbidden Depths you can get the CH-6 rocket launcher from the second forced-stop by shooting the two Malprave video monitors and use it to beat the boss quicker because its rockets travel faster than the RH-6's.

3. Also in Forbidden Depths, you can use the shotgun or rocket launcher to flip Bloch's railcar over at the start of your 1v1 confrontation with him and it will go airborne as it goes down the first slope. With good RNG manipulation you can make him land upright behind you. Then, if you shoot his railcar again just before another downhill turn, he will be slowed down but then rubberband to catch up to you, slamming into your back at the bottom of the slope. This backboost saves about a second. No video for this at the moment.
4. In Poseidon, the player can activate the elevator and then move backwards to jam the door as it closes. This allows you to leave the elevator about 5 seconds earlier.
