That is confusing work ethics with implementation strategy. One could argue that it is more ethical -- your duty to your investors, employees, employers, customers, etc. -- to focus on a more practical solution ("80%") than to seek perfection to satisfy your own personal standards. But if your responsibility (whatever it may be) dictates near perfection, then clearly that is what needs to be done. (Ex: 80% safe mass transportation system?)
