The amount of effective playtime you get from a rubber (lets call it up until the performance becomes 70-80% of new) greatly varies by user, conditions of the venues, care, the player's impact, the use or non-use of very wide edge tape to prevent early gassing out of the sponge, the amount of impact and by exactly what rubber it is.
In Korea, I palyerd every day 3+ hours. Tenergy, without edge tape maybe made it 4 weeks (100 hrs) before it became an average rubber. With edge tape, I could stretch that to 6 weeks. (150 hrs) Aurus would make it 2 or 3 months before I would switch it out. (the 200-300 hr mark) and my Korean friend would use it on his Jun Mizutani another 6 months (600 hrs).
All I did to take care of it was use edge tape (12 mm) wipe it off with my sweaty shirt, pants or hand during pauses in play, and toss the bat into my bat case after a shirt wipe-off. Carefully using BTY foam and a sponge and protective sheets did nothing to extend the effective life for me. For those who only played an hour a day, treating it like that probable added considerable life to their rubber. They would get 6-8 months out of their rubber easily, but in hours played, maybe only 150-200 hrs.
