It'll help, not because of spring tension, but because the system is smart. When you're riding on the large ring and outer half of the cassette, the system makes a crisp downshift. But when you're riding on the middle or inner half of the cassette, it compensates for the chain angle by shifting slowly and hesitating a fraction of a second so the chain can't suddenly snap inward and overshoot.
But you might have misread my post. I wasn't referring to the FDs spring, but the issue of the chain's tension when under load. The electronic system may be better under these conditions, bt don't expect a miracle. The key is NOT TO DOWNSHIFT THE FRONT UNDER LOAD.
