I could swear we already addressed this issue, but maybe it was for another member.
In any event, that's not enough of a discrepancy to worry about. There's a lot of travel to the saddles on a Wilkinson VS100 bridge, so you'll have no trouble intonating the thing. As to operation, it really doesn't matter. As soon as you touch the vibrato bar, all bets are off. You change the string length, so intonation is out the window. Also, strings don't detune evenly. If you depress the wang bar enough to flat any one string exactly one step, the other five strings aren't going to be flatted the same amount.
This has always been true of all vibrato bridges; it's not the fault of the one you've chosen. There's a new design out there that theoretically solves that problem, but I can't remember its name and I'm not sure it's worth the cost/trouble. Diving a chord is more of a special effect than anything else, so you don't worry about tuning when you do it. A bigger worry is if you go nuts, the strings may fall out of the nut slots or stick to the pickup. But, by the time you get to that point, you're well past any musical needs - you're just beating the snot out of the instrument for the sake of administering a beating.
