That's the best the software will allow. For reference, a 5/16" little stainless washer from ARP weighs right at 1 gram. The software give a fudge factor of 2 to 4 grams for 10W-30 vs 20W-50 oil sticking to the crankshaft and being flung around in the crankcase. Yes, a balance of 0-0 would be best and perfect. But a commercially rotating assembly kit within 8 grams left and right would be considered pretty darn good IMO.

Sorry I don't know which balancer Paul uses. That was a Pontiac 455 rotating assembly
