0.10 Something happens to you financially where you can no longer afford this

This one seems conceptually strange in a cost-benefit analysis: if you get into straits in which you don't want to pay your insurance premia and membership fees, then you stop paying and lose the protection (unless you have been suspended or died in the interim). In this situation both the costs and benefits are reduced, so it shouldn't play the role it does in the above calculation.

0.03 You mess up the paperwork, either for cryonics or life insurance

This rate is empirically too high.

0.20 Not all of what makes you you is encoded in the physical state of the brain

Why so high?

0.35 Other (there are always other things that can go wrong)

One does have to inform this probability by historical rates.

Something goes wrong in reviving

A lot of these claims are going to be correlated with each other and brain preservation adequacy (from the first section), likewise for technological/economic capacities and interests. If you apply a mistaken independence assumption and break apart many correlated things you'll get big underestimates of probability.
