Good question. First there are two equally acceptable ways of measuring tiller. One is to just bottom both limbs and back them out equally. NOW, assuming that both limbs are matched and have the same deflection then all should be well.
The seond way is to stretch a a string from axle to axle and measure to the shooting string from this. Adjust as necessary to get even tiller. Here again, if both limbs are matched then the tiller should be even with the limbs turned out the same.
There are circumstances where you might want it to NOT be even. Say that when you aim the bow your pin settles just below a spot. It coiuld be the weight or just the balance of the bow that causes it. In this case you could turn the bottom limb in a quarter turn or so. This will put more stress on the bottom limb and make the bow aim better. It's trial and error thing and done mostly by target shooters. In any case it's not something you get carried away with.
However, changing the tiller also changes the nocking point in relation to the rest so a slight change to this might be necessary. Again, it's something you have to play with to determine what works best for you.
And this is why us tinkerers tinker. We love to break the rules and change them to suit ourselves. There are just no hard and set rules in archery.

Just to add a bit to bfisher's great response, if the tiller is off too much it can affect the tune of the bow. Remember that tiller is distance from string to top & lower limb measured at identical points on each limb. If one end is off enough in essence each limb is flexing, loading and working differently than the other limb. The further the tiller is off the greater the difference.
Some finger shooters intentionally tune this way especially those that release with 2 or 3 fingers under and none above. They do this to compensate for the fact that their fingers are putting more stress/load on the lower 1/2 of the string and in turn to the lower limb so they MAY find it best to set the tiller slightly different from top to bottom to best tune for their style.
For release shooters general rule of thumb is to have the tiller as close to even as possible.
Hope this helps.
