Quoted from Taxman:Short answer yes. But reasons are debated.
Some say the wood is compressed, some say the old wood is harder.
I just wonder. If it was compressed wouldn't all old and compressed playfields had distinct higher areas where the ball can't reach? Like the last 1/2" around every post and the sling shot area?
The dimples, for the most part, are in the clearcoat, surely?
They result from the ball compressing the clearcoat, and if struck hard enough, then the underlying wood. The difference is that the wood will rebound (though over time becomes compressed and harder). Since the larger strikes and drops won't compress the wood as much in older pfs, dimpling of the clear won't be as pronounced.
That's my understanding.
