I think with the current implementation, it would make more sense to keep all the uptime checks in the calculator. If the calculator returns 0, we don't release any rewards which is totally fine.

return (stakeAmount * rewardBasisPoints * (stakingEndTime - stakingStartTime))
/ SECONDS_IN_YEAR / BIPS_CONVERSION_FACTOR;
}
