1-2 months
Real good question but super subjective, which is awesome! When I was a broke kid, they lasted till they broke, when i was single they lasted until I stopped at shop, when I worked at shop they lasted a day, now they last a whole season since I'm married.
If you don't want to ride it, replace it. there is nothing better to be stoked about! I like how users had hours configured. I skated whatever I could. The spot picks the weak part. I used to skate ledges when my tail cracked to get an extra day even.
BEST ADVICE EVER: SKATE HARD, BUY THE BIGGEST CHEAPEST BOARD YOU CAN FOR A SPARE, KEEP IT AROUND, IT'LL LAST A WHILE AND YOU CAN SKATE NO MATTER WHAT.
