Those settings are in the right ballpark, but you should be able to go 50% faster with no issue, at least in pine. But in v-carving a critical parameter is also depth per pass, 0.1" should be fine in pine, while 0.05" could be your starting point for hardwood.
when you are lucky the size of the flat is mentioned in the tool’s specs, but more often than not it isn’t, and then you just have to estimate it. @neilferreri provided a nice spreadsheet that will tell you how much to raise the Z zero depending on the size of the flat and vbit angle
