I've been wondering for a while about how the inner gate wheel works when it comes to incoming wormholes. When dialling out the wheel turns in order to move the glyphs to the corresponding chevrons. But when a wormhole is incoming, does it need to do the same thing in order to open? In most episodes, the wheel turns for a few seconds, locks one chevron and then opens. I'd have thought that it would need to dial all of the incoming planet's symbols in order to open. If that is the case, how would the gate know which symbols to key in when the wormhole hasn't opened yet?
Am I getting confused or making any sense here?
