Doesnt hurt to have off limits lands within an sra either. lol.
The same reason huge majority of record book entries come from the very limited land area that are the sras is the same reason why more buck are left post-season. No access which equates to protection from the deer management program.
Everywhere else there are VERY few legal buck still alive post rifle season. I didnt say "none" but pretty danged few. lol.
Our lack of "big buck state" status (about as far from it as possible to be) also points out exactly how many legal buck we carry over from one year to the next.
