If it's your first time making soap, I don't advise a 10oz. oil batch. At 0% superfat (you want at least 5) it would only need 1.44 oz. lye. I would run the recipe thru soapcalc.net using the ounce figures, then switch it to go by percents and raise it to at least 16 ounces, 32 even better (small batches move fast, and if you are trying to be careful the first time you may feel a little rushed) I suggest using the 38% water as oil weight that soapcalc defaults with (which is just a little under the 4 ounces you have) When I change the percent numbers using your oils, I think 30% avocado, 25% olive, 25% coconut, 20% palm is what I would probably like, although I would love 5-10% shea or cocoa butter in it also (cocoa butter is sold in most cvs's, a one ounce stick in the lotion aisle and it should cost $1 - $1.50, so it's an easy way to test and see if you like before buying in bulk.
When you say hp, do you mean you are pouring into mold and inserting mold into oven, or cooking soap in a dish or crock-pot and then pouring into mold. I don't like using more than 38% water in cphp (crock pot hot process) because I find my soap warps as it dries if I use too much water.
