Best I can provide are ballpark numbers. For example, discharging to 25% may be equivalent to 10% of a life expectancy cycles. 50% discharge may be equivalent a 35% or 40% discharge cycle. And (of course) a 100% discharge would count as a 100% discharge cycle. Ballpark numbers that only demonstrate the trend.
Another factor is how fast a discharge occurs. Some batteries last longer if each discharge cycle is slower. Or if power drain does not involve high power demand spikes. If computer useage involves repeated sleeps or other 'low power' operations, then again, a battery discharge is not as destructive to life expectancy.
Specfic numbers are difficult to obtain.
