I am the RTA world record holder (57:02) that this TAS is based off of. Proof is here:

There are two ways to handle a TAS of this game: maximum speed, or maximum score. For maximum score, due to how the scoring calculations work, it is favorable to sometimes allow the enemy to attack first. The power score is calculated by total damage dealt, plus number of KO bonuses (each KO is +100), divided by total number of attacks. Therefore, having the enemy attack first allows a counterattack, damaging the enemy unit, and thus allowing the enemy unit to be 1HKO'd the next turn without using an extra attack. A TAS that focuses on maximum score involves more RNG manipulation and can be more spectacular. For example, the maximum score for T9 Hourglass (which is a trial map and not part of this TAS submission) involves a 0.6% luck roll
only if the RNG seed is favorable:

As for maximum speed, the RTA uses strategies that strike a balance between speed and reliability. They have a high likelihood of working without many reloads. In the RTA WR, there are still several reloads simply because I lost the luck roll. However, the RTA WR strategies aren't the theoretical fastest strategies, as those would require luck rolls that are much less likely to happen.
Someone in the community, dxdydzd, who published the T9 Hourglass strategy above, has published TAS maximum score videos for 18 of the 26 campaign maps:
https://www.youtube.com/watch?v=CjZAHJTLHNI&list=PLETr2TbRLvb6kg4uSp4HclLrK53wc4QUv. The strategies themselves are very unlikely to be improved for these 18. As for why there are 8 videos missing, it's because there has been no published walkthrough for them. There was some drama in the community because a number of people claimed the WR score for these maps without posting any video or text walkthrough proof. We were supposed to trust them and believe their high scores based on their reputations.
Therefore, while I am flattered that my RTA WR run was a blueprint for this TAS,
I don't feel this video should be approved. A TAS has the possibility to do much more outrageous tricks than what the RTA WR can do, and I don't feel this submission shows that. It does not go for maximum speed, nor does it go for maximum score. It is essentially just an input and luck optimized version of the RTA WR.
