look at what the test data says, not what an engineer says. ASTM E84 Steiner tunnel test (providing flame spread ratings) was notorious for not capturing dripping molten behavior of thermoplastics. That is because the fuel used to melt off when mounted at the top of the apparatus. PVC in many formulations is thermoplastic. Just because it is Group C doesn't mean it won't burn well.
If it is stacked 12 ft high, you got high piled storage, by prescription.
