Gravity by definition is a concentration of sugars independent, but referencing volume. So to answer your questions - both a higher gravity and lower volume.
If you sparged and ended with less volume of wort, and if your efficiency was more or less the same as before when nailing your volumes, then your pre-boil gravity should be higher. Caution here in that gravity can striate in the kettle when sparging, depending on how well the wort is mixed. If your volumes were the same - then the additional gravity could be attributed to higher efficiency in extraction. In this case, perhaps a mix of both higher efficiency and lower boil volume.
It appears your boil rates varied slightly - perhaps due to higher humidity out there in Florida today?
I am impressed that you can measure your boil volume out to 0.65 gallons of difference!
