No staking action allowed during the last quarter of the last session of the era?

Hi,

I read an article here and maybe somewhere. It says

In Polkadot and Kusama there is an election period in the last quarter of the last session of the era. In this election period, it is NOT possible to carry out any staking activity: you cannot select or change your validators and you cannot claim rewards. This is due to the fact that based on the current information of validators and nominators, the Phragmén algorithm is executed offline to select the validators and nominations of the next era.

Does it mean 1 hour in the era user could not do any staking related actions (e.g., bond, unbond, nominate)? I try it and also observe the events on explorer but cannot see such restriction. Need some guidance.

Thanks,
Wesley

Hey @wesleywen

I believe this is correct! Also seeing it discussed in the wiki. Although the last quarter of an era would be 6 hours, I believe. (24/4)
