 > Note: Ideal scenario assumes no block proposals are missed. This means a total of withdrawals of 7200 blocks/day * 16 withdrawals/block = 115200 withdrawals/day. 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.
