Oil isn't completely predictable. Different strains and different ages of material will give you different results occurring at different temperatures.
If you are playing with the same material every time then it's more predictable what temps and lengths of purging will take you to where you want to be. But if you are playing with different material all the time you will find it's a learning curve all over again.
You should be able to shatter at 90F then keep it purging and raise the temp up gradually till you get wax. But do it very gradually in small increments cause if you go to warm too quick you will end up with the dreaded GOOOOOOOOOP
