Yep. Pretty much. From stress testing done by others, it appears that value is ~3,000 for the Samsung 830, ~1,000 for the Samsung 840 and ~1,100 for the Samsung 840 EVO. Once raw WLC reaches those numbers, that's probably when normalized WLC reaches 0 (or 1, can't really remember what the minimum normalized value is for Samsung). Actually, not much need to look at raw WLC for drive life. Unless you know the P/E cycle rating, it's pretty meaningless anyway. All you need to do is monitor normalized WLC.
No idea what the P/E cycle rating is for the 840 PRO but once you hit a normalized value of around 90-95 (around 20-40TB writes), you can use the formula I posted to get a rough estimate of P/E cycle rating.
(Raw WLC / (100 - Normalized WLC)) * 100 = approximate P/E cycle rating
