Cheapstaking strive for transparent results, at the start of each new epoch previous results will be displayed showing the number of blocks minted, the return on staking and the slot allocation for the up coming epoch. 

100%  = All assigned Slots were converted to blocks during the previous Epoch
ROS% = Annualized Return on Staking – your percentage return based on your delegated staking. You can use this % in our calculator or multiply this percentage by your total stake and divide by 365.
-> = Upcoming slots and total stake for the current epoch

Slot  allocation are randomly assigned to pools during the new epoch transition, our pools are online 24/7 with monitoring and automation to ensure nothing goes a miss. Do be aware having a slot does not mean a block will be minted – its possible multiple pools will be battling to produce a block on that slot as the different battle types described below:

• A SLOT BATTLE means two pools were assigned the same exact slot. If the network is working well, both pools will use the same parent block to build from and then the first pool to distribute their block the widest and fastest to all the other nodes will “win”
• A HEIGHT BATTLE means two pools tried to create a block with the same parent hash. However, they were assigned different slots. Ideally the pool with the slot ahead of the any other pools should always win – as they have a competitive advantage (they can make their block in advance of other pools). However, in practice you could make a block first, and still not win if another pool is connected better to all the other nodes.
