As of 2019, over 400 people have been cryopreserved (175 at Alcor, 183 at the Cryonics Insitute, 71 at KrioRus), and many more people are members of cryonics organisations with arrangements to be cryopreserved after their deaths.

Cryopreservation currently involves replacing blood with a cryoprotectant and slowly cooling down a body to liquid nitrogen temperatures for long-term storage. The hope is that this preserves enough of the structure of the brain that, with advanced enough future technology, revival will eventually be possible.

Chances of revival may also be increasing over time, as cryopreservation techniques become better and the institutional knowledge to get people cryopreserved sooner after death develops.

I thus ask to what extent revival will be possible for people preserved in the next 30 years:

What percentage of people who were initially cryopreserved between 2020 and 2050 will be revived by 2200?

"Revival" means that the person would be able to meet the standard described in this question; either through conducting that specific test, or by some measurement that is equivalent such as official statistics on the health of revived patients.
