I'm not sure I agree with this statement completely, at least not over the last 5 years of the W.R. A tag being valid for rifle cow elk during the same timeframe as the general deer hunt. I saw plenty of folks working hard for cow elk and shooting deer that they even admitted would have never happened without the seasons coinciding, alot them said they simply wouldn't even be in the unit without rifle elk tags and deer were added to the hit list because "why not maximize the potential for success of any kind." Most of those same hunters had a long history of hunting the W.R. B tag which obviously takes place after the general deer season had closed and felt it wasn't worth the expense, effort or missed work to come earlier and hunt a 2 point without an elk tag in their pocket.
Plenty of guys also drug their kids and wives out to have more elk tags in camp and of course they also had deer tags, the majority of wife/kid demographic didn't work hard for elk at all, but they whacked plenty of easily found does and 2 points and some their elk tags got filled one way or another. Just another factor to ponder, I'm no biologist but my eyes work just fine and I saw it first hand the whole time that the rifle cow elk and general deer seasons coincided.
