I hope those numbers hold up for you on the golf course.
I rarely go to the driving range, due to back issues. However, I've found that unless the range uses natural grass (which none do around my town), I don't put much stock in distances. So many swing and club-contact faults are covered up by artificial turf. Just my opinion of course.
I agree, that artificial turf will make you think you are hitting much better than you actually are.
