I'm fairly new to bow hunting and have a couple questions. When you say the arrow weight are you just taking the gpi and multiplying by length of your arrow and then adding the weight of the broadhead your shooting?? For example my arrow shows me 9.3gpi and shoot a 28" arrow = 260 then 100gr broadhead gives me a total of 360? Any help would be appreciated. Thank you,
