no
Have you ever placed a screw leading on steep ice?
I've placed screws on lead, thought nothing that a hardman such as yourself would consider steep.
But what if a guy goes out and solos Carl's Berg. It's rated WI5, and is in good condition. Did he just solo a WI5? According to you, no, because it was easier since he didn't have to place any pro. Likewise, if you place a screw every three feet, the climb will be harder than if you place pro every fifty feet. But it's the same climb.
