About 30 percent of option exercises are followed by no share sales within thirty days.

The 30% figure you cite is artificially high insofar as it includes options that are expiring imminently.

If you consider only options that have, say, six months or more until expiration, the proportion of option exercises that are held is much, much less than 30%. I would wager that it’s less than 2%.

p.s. Directors, executive officers, and 10%+ shareholders must report their purchases and sales on Form 4 within two business days.
