It depends on the Software-Version at which speed the recuperation is activ and yes, there is a significant difference between the two levels. To prevent the battery of overcharging the recuperation is not functional if the battery still is in a good shape and has enough capacity. With the actual software the battery could be charged by recuperation if the capacity is below 70%.

As a "motorbreak" the recuperation makes sense but if you know the chemical issues in a battery you know that short recups makes absolute no sense because the battery is not able to store such charges.
