The peculiarity was that while the disparity between the two was greatest on clay of all four surfaces, each of the three times Martina did win, it was a route.
You also have to take into account that Evert finally switched from wood to graphite around that time and had a few bad losses as a result since it took a little while for her to really start to feel comfortable with the new racquet.
Also playing absolute peak Navratilova, playing with graphite, with Evert still using her beloved wood racquet before she switched was a factor in a few losses too.
