Yeah, I kind of intentionally avoided saying AFPS because unfortunately these days that tends to mean (like with diabotical) games which are desperate to be the most hypercompetitive aspects of quake. Duels or FFA aren’t really my thing, give me teams and objectives!
Perhaps unsurprisingly UT2k4 is one of my favorite of all time
When they say something like “60 days battery life” what they mean is using the device for half an hour everyday for 60 days.
OP is arguing that it would make more sense to just say the continuous use battery life, which in the above example would be 30 hours (60 × 0.5)
