You just had a lucky streak. They come and go. PL mostly doesn't matter for the rare mats.
I have 42 ~PL1000. Some times they might bring me 4 phazons in one day, other times I won't get one for 2 months. The only thing that helps is a higher frequency of mats being returned, which means more monsters and higher PL/chaos.
May be. But I'm satisfied enough. I've already gotten far more than what I invested in monster lab.

I've had this experience, too. Like most mechanics in this game, quality doesn't matter.. its all about frequency or quantity.
True.
