“It’s inserting a driving line which is an arc, between entry and the start of full acceleration. The ‘arc’ driving line is able to be taken at a speed slightly higher then entry speed. It can be taken at a speed higher then entry because of dynamic redistribution of weight more evenly across the outside tires. … Instead of turning in and riding a ragged edge trying to get as much acceleration to the point where the straight takes over, you roll through the turn a little on a line which is an arc, at a speed slightly higher then entry, then make your final turn and controlled acceleration onto the straight.”
But how can you travel at a faster-than-entry-speed rate at apex without accelerating? You can’t speed up without accelerating.
