Hi Jam35X.
If you are staking, you will always have a proportional chance to be elected slot leader.
The 2% criterion is for being on the ‘electoral committee’ - these will participate in the coin flipping protocol (termed the ‘Multiparty computation’) and the choosing of all slot leaders for the next epoch.
Here’s the details from the docs:
Slot leaders are elected from the group of all stakeholders.
Please note that not all stakeholders participate in this election, but only ones who have enough stake (for example, 2% of the total stake). This group of stakeholders are known as “electors”.
Electors elect slot leaders for the next epoch during the current epoch. Thus, at the end of epoch N it is already known who are slot leaders for the epoch N+1, and it cannot be changed.
Imo - I think 2% is unrealistic requirement (and 2% is only mentioned as an example…not finalized) as that means effectively you would never have more than 50 servers on the election committee and it’s unclear how many staking pools/stakers would be large enough individually to host 2%. (Note that is 2% of the total staked at any point, not total Ada).
Anyway, just wanted to clarify that the 2% is only specific for being on the election committee (an elector) and is not a requirement for being a slot leader and thus getting staking rewards.
You can have 1 Ada staked (and with a lot of luck lol) still be a slot leader
