This will vary a lot...
I was doing 120s for 15 or so and maxed out 460 bb after a set of 405x3 end of high school.
There are different muscle types; fast and slow twitch.
It's the same question as: "If I run a 6 minute mile, how fast can I complete a marathon or long distance run? ". The answer will always vary.
For a 315 bench max, you should be able to handle the 100dbs for at least 6 to 8 reps at a minimum; 12 or more would be more ideal and proportional. Again, it can vary, since db utilizes a whole different set of muscle groups.
100s are my 225 equivalent i would say. You get 100s for 10 chances are you will get 225 for 6-8 minimum.
