Seems high to me....
I'd estimate about 60 ounces of flour? Rule of thumb is that fresh yeast is about 1% of the flour weight. That's .6 of an ounce. Of course, that's designed to give the bread enough time to develop flavor. If you're looking for a quick bread, use more.
BTW, most bakers don't bother with fresh yeast anymore. There is no flavor difference. I use .003 * the weight of the flour to determine the quantity of yeast. So, your 60 ounces (assuming that's correct) is around 1700 grams of flour which would call for five grams of instant yeast. And don't forget the 34 grams of salt.
I'd suggest about 5% honey. Works well for me. Why sugar too?
I've recently gotten into grinding my own flour. Sunday I did 200 grams hard red wheat, 300 grams hard white wheat, 50 grams spelt. I sifted the results to remove some of the bran, getting a 90% extraction, or 500gm of freshly ground flour. That fresh flour has an acid that not only tastes bad, but is bad for you too, so it needs to soak in water overnight. Knowing that I like a 50/50 mix of KAAP and fresh ground, I'd have 1K of flour. Since i'm mixing by hand, I wanted a 75% hydration, so I added 750 grams of water to the 500 grams of fresh ground. With an overnight soak, it's good to add the salt now so my 2% salt is 20 grams. That's 500 grams fresh ground flour, 750 grams water (room temperature) and 20 grams salt. Mix and cover overnight. The next morning, add 50 grams (5%) honey to the fresh ground flour mixture. Pour that mixture into a large work bowl. Sprinkle with 3 grams instant yeast and 500 grams KAAP flour. Mix by hand and go from there
