Test it (SG and taste test). It was probably mostly done at day 4, which means you shouldn't have much trouble with off flavors, even though it got warmer later. An old quilt is a good thing this time of year. It damps out the temperature variations.
I'm hoping the yellow jacket season is almost done. A few more 40F nights and some cold rain & I'll be able to brew & BBQ without the ack-ack guns!
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
