Update:  Please update the miner to v1.1 because the first version had connection problems to Nicehash EU stratum from different areas and got stuck "retry after 5 seconds".
The new v1.1 version  will mine on Angrypool when switching to Dev Pool Dudes pool on the Fee time.
Also the CYCLE_TIME  between pool changes increase like you asked.
Please let me know if there is any more problems.
