What’s the Right Power Amp Ratio For Bi-Amping?

Is there a “golden rule” or rule of thumb when selecting amplifier power in a bi-amp setup? It seems to me that the power should be apportioned according to the demands. Since most of the energy consumption  in sound reproduction is by lows, it stands to reason I should use a much more powerful amplifier for lows than highs, but what ratio of power? 2:1? 10:1? Is there a wrong answer?

With speakers that have seperate terminals for LF and HF, doesn't that remove the problem with both amps sharing the same load? Or does it not matter because the amp "sends out" the same signal regardless of what it is connected to?

For example, Tannoys have separate terminals, and Tannoy say they are biamp ready. Would they bother if they didn't feel there could an advantage?
