Mine says 9 or faster. Realize that just because your barrel is supposed to be a certain twist doesn't mean that it is that twist rate exactly. Do the cleaning rod test and measure accurately
If you reread the email straight from Berger that I posted, it states that they have tested the 195 in barrels as slow as 1-9.3" and the bullet maintained stability
Confirming a barrel's actual twist rate is a given before a bullet ever passes down the bore, but Berger's numbers are based on actual twist rates.
In the email it says that you can go as slow as 9.3" to maintain MARGINAL stability. According to Bryan Litz, a bullet in the marginal stability range with an SG between 1.0 and 1.5 will lose about 3% of its BC value for every 0.1 SG under 1.5. Maximum BC is realized for anything over 1.5. Hence the reason for my wondering if you'd see higher than advertised BC values if you had a faster twist rate, if you are indeed under 1.5 in SG, of course...
