With all due respect, I don't see that as the gist of this forum. (the following is just using this as a jumping point, not a direct argument against you.)
The forum is specifically for those in the trade, not laymen and sometimes the best information here is found in the diversion. As such, if the answer is simple, then the OP should be challenged to come up with their own answer, not simply answered. Please feel free to correct me if I am wrong. I am not trying to speak for the forum, but this is the way I interpreted the forum information years ago when it was presented to me by the great Dennis Alwon, a lowly moderator at the time. (Oops, not that is an off topic diversion)
This also isn't a disagreement with iWire's original post as I interpret it, which is more about straying off topic, not delving more deeply in to it.
OP: "How often do you have to strap conduit?"
Proposed answer, "What research did you do before you posted this question here?"
