Peter;
That is indeed an interesting statement!
Almost the polar opposite of the commercial exhortations of today....' buy the longest, hottest, balls.......' and the spongy green turf that those balls are used on.
And it's consistent with the fescue regime here, where fast and firm here is fastest and firmest in the late fall, after a long dry summer and a sunny but cool fall........around November the ball is rolling all over the place!
Good to see you here recently,
Tom
