NSO N64 controller has greater input lag than the Gamepad

[al797]

I own a NSO N64 controller but don't own a Switch so unfortunately I can't say this is an issue with the controller itself.
On the Wii U, at least, I can tell there's noticeably a higher input lag compared to the Wii U Gamepad. Is this something to be expected due to how Bloopair handles these officially unsupported controllers or is it something that might actually be improved?
