(socrates, etc) started talking about how well it worked. There are issues. Convergence can take several iterations, the more iterations, the quicker your tree size passes normal PVS and it begins to cost rather than save you. There are quite a few internal mods you need to add that you don't necessarily need for normal PVS. You need to store both upper and lower bounds in the hash table. You really need to consider ETC even if you don't do it in your PVS program (I don't). Some swear by it. Some swear at it. You pay your money and take your chances. It works quite well for some. It didn't for me...
