Practical scenario assumes 1% of blocks are missed per day. As an example, if there are 700000 eligible validators, one would expect a waiting time of slightly more than 6 days.

    The total time taken is the summation of the above 3 waiting periods. After these waiting periods, you will receive the staked funds in your withdrawal address.
