Is the bow's design symmetrical or asymmetrical? How do you grip the string?
I dynamically balance my bows relative to my holds, design them so their center is near my fulcrums, and many, perhaps most of them end up with equal or nearly equal tiller measurements. But if your bow is symmetrical and/or you hold the bow and string differently, not to mention the vagaries often inherent in a wooden selfbow... an even tiller may not be best. Sometimes it's not what's best for my bows either. But in the end, I know and do what's best... tiller measurements be damned. Each bow is balanced at full draw relative to my holds with total disregard to brace height measurements. They're a virtually meaningless end result.
In short, nobody can accurately answer your question as posed.
I say, balance the bow at full draw relative to your holds, and let the brace height measurements be whatever they'll be. You wont know what they are, nominally, until the bow is done, but you KNOW the bow will be right.
