That is a little bit on the low side, but should be ok. It's a matter of compression and voltage. You're spinning a 9.5:1 motor with a tiny battery, so it's going to crank slow. As an experiment, you could temporarily hook up a full size battery (even with jumper cables) and see if it spins faster. My car cranks about 100 rpm faster than yours with a "full size" miata battery.
