It just seems iffy in general, it literally clips through some characters arms and won't hit, it seems to actually work on larger fighters like bass and Radio without the clipping. probably because of bigger hitbox.
I wouldn't worry too much about it. It might be an issue at R1F, but other than that just keep in mind that you have to be closer than R1F to hit Eliot. My suspicion is that it has something to do with Eliot's natural movement while standing still. Some characters move more in default position than others. For example, Jann Lee moves way more than Gen Fu while idling.
Something is wrong with Naotora's 8P, its 1.54 in distance and will randomly hit and not hit Eliot, even though it's close enough to practically hit. Its not his stance as it has little movement and i tested it at roughly the same times i reset. Be careful using it, it would appear her only safe mid punch has hitbox dissonance 0_o ...TN, either fix this please or explain why this is occurring, this is literally her only safe mid punch in neutral.
