Problem  8.8.2   
Cristian Wuthrich and Stein (mostly Wuthrich) have written a bunch
  of code related to using Peter Schneider's work on 

-adic
  analogues of the BSD conjecture to compute 

 at certain
  primes where the methods of Kolyvagin and Kato fail. 
 Remark  8.8.3 (From Christian Wuthrich.)    
Note that the paper mentioned above, as
  far as I have written it is, to my taste, more or less done. I
  should add some data of numerical results which you can of course
  ask the students to produce. But there is no need or interest for a
  long list. I have not written yet the introduction nor the part I
  named technical details (but I am not sure if I actually want to do
  that).
Of course, I am very happy that part (or the whole of) shark will be
  included in SAGE.
 Remark  8.8.4 (From Christian Wuthrich.)    
Schneider's (and simultanoeously
  Perrin-Riou's work) is strictly speaking not on the p-adic BSD. The
  most important result to use is Kato's which links the algebraic to
  the analytic side.  Look in the article we write together for a
  tigher bound in the case 

 is not zero. Your katobound in
  sage is not sharp.
