No, you don't. The same volume of gas, and therefore the same Btus, will be output on an given analog hob at a given setting, no matter what. This is not the case with induction, with its discrete digital settings, cycling, PID control and standby modes.
Let me give you an example. Suppose you want to assess the evenness of Pan A, and compare how it performs on one induction versus one gas hob. The easiest (and fairest) way to do this is to pick your discrete induction setting, and let the pan come to thermal equilibrium. Take your readings. Choose a sensible location, usually dead center. What is the temp at that location? Then fire the pan over the gas hob. You dial the analog valve to the point where the same location comes to equilibrium at the same temperature. Take your readings. Compare.
If you try to do this the other way around, if you have a good thermocouple, you'll see a difference, because you may not be able to match the center temperatures with precision.
This also points up that the old-fashioned analog gas valve is infinitely variable within its range. Not so with induction. The practical difference here depends on the granularity of the available settings on the induction appliance--the finer the granularity, the closer to infinite variability. Control Freak and the Vollrath 100-step units offers good granularity, but their chief virtue is repeatability.
