I've been using a 16T difference at the crank since since 2008. I have no issues with the compensating shifts. If the shift is timed right, where your cadence has dropped from the climb, you can shift to the little ring with no compensating shifts. It all depends on how quickly the grade is increasing. I rarely need a 3 sprocket shift. If the change in grade is slow, and you shift well ahead of need, shifting 2 sprockets smaller immediately before the shift to the little ring can work, but on a fast increase, you can get bogged down and have a poor chain ring shift.
I'm not impressed at all with electronic sequential or compensating shift modes because it contributes to chain drops and can make unwanted chain ring shifts. I use SRAM force axs 12 speed and never use the compensating or sequential modes. I limit my shifts to 2 sprockets if I hold the shift lever, there's no over compensating. I also don't use a sram crank because I want the extra range of a 16T difference.
