Hello SalamenceShiro and welcome to TASVideos. There exists a TAS created by Meerkov that I'll be using as a comparison to your TAS. The difference is they completed their TAS before World Championship, as it would just be the same copy pasting the same results. Marked in bold is the better result in the comparison.

Event	Meerkov	SalamenceShiro
100 Meters	8.91 seconds	8.91 seconds
Long Jump	9.21 meters	9.20 meters
Shot Put	33.32 meters	32.40 meters
High Jump	238 meters	238 meters
High Jump Extended*	247 meters	250 meters
400 Meters	41.25 seconds	41.25 seconds
110 Meters Hurdles	11.36 seconds	11.36 seconds
Discus Throw	106.44 meters	110.77 meters
Pole Vault	530 meters	530 meters
Pole Vault Extended*	540 meters	540 meters
Javelin Throw	88.69 meters	82.86 meters
1500 Meters	3:29.50	3:29.50

But, as you did World Championship as well, that gets compared to your previously compared input, as it would've have been as simple as copy pasting, in theory, in practice with your results compared:

Event	World Championship	SalamenceShiro
100 Meters	8.91 seconds	8.91 seconds
Long Jump	9.29 meters	9.20 meters
Shot Put	33.09 meters	32.40 meters
High Jump	238 meters	238 meters
High Jump Extended*	250 meters	250 meters
400 Meters	41.25 seconds	41.25 seconds
110 Meters Hurdles ^	11.36 seconds	11.36 seconds
Discus Throw	110.26 meters	110.77 meters
Pole Vault	530 meters	530 meters
Pole Vault Extended*	540 meters	540 meters
Javelin Throw	82.86 meters	82.86 meters
1500 Meters	3:29.50	3:29.50

* Extended is continued after the best height cleared, it allows for more points. ^ A false start is called at the World Championship which makes me wonder if it's possible to manipulate and avoid that situation, as that would not cost time. I also have to ask, what about using wind? Wind does have a significant advantage if it was used, I was actually able (shockingly) to unearth this old input and can provide it for you to look over and compare, it uses BizHawk 2.6. The table provided here, is showcasing what's used with wind in comparison to your best results without wind.

Event	Spikestuff (wind)	SalamenceShiro (best, no wind)
100 Meters	8.91 seconds	8.91 seconds
Long Jump	9.33 meters	9.29 meters
Shot Put	39.17 meters	33.09 meters

And showcasing my input, I reminded myself about something in Shot Put. Don't throw far after setting your best attempt. You want to immediately throw the ball as soon as possible to get by the event quicker instead of throwing far or throwing far and fowling. This is nice work overall, but there are little errors that can be spotted by comparing to the other existing run, and I'm interested on your further development on this game, as well as some optimization cleanup that could be made such as what I wrote about Shot Put and within Long Jump where you prepare your run at frame 2895 but you can start as soon as 2891. What I wrote could be within error after all, when you compare my shot puts for instance where an exact same throw results in a difference of 5cm. A Light Spike of 6351 frames to fix the overextended input.
