lol. Not at all. Firstly, I'm not validating ANY theory, just saying there are 2 possibilities. Secondly, the reason I restricted the theory to split timelines, is because that is the only place there is a dispute. There is no question if Tingle can travel between two seperate timelines via Termina in a single timeline, because there isn't another timeline to consider.Here you're using one theory (of two separate timelines being created at the end of Ocarina of Time) to validate another theory (that Tingle met with Link from timeline A and then ran off to timeline B).
Let us compare:You're not addressing the question - how is suggesting that the seal was renewed off screen inbetween TWW and LttP any worse than suggesting that the sealing took place off screen inbetween OoT and LttP?
The idea of the seal being renewed was never mentioned in any game and is purely fanfic. In fact, it goes against the canon as aLttP mentions Ganon being sealed and suggests he never left before aLttP happens.
The idea of the seal being created in Child Link universe between OoT and aLttP is the only way that all facts can be true. It also uses the exact booklet information so it doesn't rely on fanfic like the above idea does.
