He gets out at 51. Somewhere around there with 25 year sentence at 31 with credit for time served.

how, he is 32?

I think its probably taking the approximately 21 years you get with the sentence with maximum good conduct time reduction, and also assuming credit for time served after his bail was revoked.

32 years old + 25 year sentence +/- 15% good behavior / time served / whatever = 57 years old at the oldest

That is a big difference. You can live a pretty good 15 or so years if you get out at 60. Considering that his parents are well off he will inherit some.

Almost anyone who is deterred from committing the crime if they get 50 years will also be deterred from committing the crime if they get 25 years.

He's got 11B in restitution to pay. Any inheritance he gets will be forfeited to that.

> It is long enough to destroy his life.

Hardly. Milken was sentenced to 10 and served 2. SBF will serve 7, at which point he'll still be under 40.

Milken got a sentence reduction for cooperation with prosecutors against others. The other big fish in FTX already cooperated against SBF, who do you expect him to roll over on?

The federal system doesn't have parole, and gives a maximum of 15% off for good behaviour.

He won't be out for ~two decades.

and its not even a true 15%, its less than that

This is not correct. Federal sentences do not have parole and can be reduced by a maximum of only 15%, meaning (if that happens) SBF will serve at least 21 years and be 53 when released.

Milken was released because Trump pardoned him, which I don't think says anything about how sentencing guidelines do or should work.

> Federal sentences do not have parole…

TIL, thank you! That makes me feel much better at what initially seemed like a slap on the wrist.

> Milken was released because Trump pardoned him,

He was released after a sentence reduction for cooperation with prosecutors against others decades before the pardon. Both the release and pardon occurred, but the latter was not the reason for the former.
