Perhaps you and the other climber are as talented as you say? I cannot say, your comments appear as though you are trying to earn fanfare. This isn't the type of dialogue I envisioned, especially from veteran climbers.
Lesson learned: Ropeless solo can be safe providing the tether is as dynamic and strong as a climbing rope or actually is a short piece of climbing rope. Building anchors and training this way is extremely slow and would never be viable on a multi-pitch true-aid climb because of time limitations.
I respect expert climbers and welcome constructive criticism.
