Each item converted has a 1 in 72 chance of giving the correct type materia of which you need 8 different types which leads you to have an 11% chance at getting one correct materia per gear converted. Mind you that 11% will diminish by 1.38% for each complete tier of materia until you are on your last remaining required materia at a pathetic 1.38% chance. You need to obtain 75 materia.

That is some weird Math there.. 1 out of 72? Kind of made up, since not every piece of gear can be converted into every kind/tier of materia. So recheck some of the Basics, before you present some percentual value's, then we can continue. At that point it may does not look as insane to you anymore, as it may does right now.

Oh and yea, what the other people said also; if it is not the correct one, you can sell it and buy the one you need in exchange. Not really that hard.
