Well, the logic seems sound at a glance, and since the text does show the bullet going through 20+ layers and the layer-to-layer distance being infinite in size, this looks good at a glance, but I'll tag some staff to check it out who have had experience with topics like this.

Also at Infinite Speed feats you pretty much have to resort to being Infinite Speed all round since at this point distinctions between flight speed, combat speed and reactions become
effectively meaningless. You'd pretty much need Infinite Speed Combat and Reaction speeds to cope with Infinite Travel speed in any sensible manner.
