Is This True about A Compression/Leak Down Test?

I'm looking at a 91 964 Turbo and called a well known shop with 40 yrs experience to get a PPI done. When I asked about the compression/ leak down I was told on these 964/Turbo cars it wont be accurate, the reading will be all over the place. He also told me Bruce Anderson had a write up on this in Excellent magazine.

So where does this leave me? How do I know the engine is in good shape?
