 * Percentage of your hashing power that you want to donate to the developer, can be 0 if you don't want to do that.
 * Example of how it works for the default setting of 1:
 * You miner will mine into your usual pool for 99 minutes, then switch to the developer's pool for 1 minute.
+ * Since v2.5.1 start time randomized in range from 50 to 150 minutes minus donation time.
 * Switching is instant, and only happens after a successful connection, so you never loose any hashes.
