I don't usually use the summer bee meadow calculator but I ran a recipe through there to compare with soapcalc. It appears summer bee meadow gives about 10% more water than soap calc. So if you reduced soapcalc's water by 10%, you should get approximately the same amount of water as what summer bee meadow would have given you. It could also be that this particular batch was unscented. Sometimes the fragrance can speed things up a bit, so by leaving it unscented, the process could take a bit longer. But since you need to cure for a few weeks anyway, the end result shouldn't really be different.
