Nice!!! Now S70 become a 1k base, and it is now the 1k Sierp base with 2nd largest CK (the 1st largest CK is S430), and if proven (I think that both this base and S430 can be proven when tested to n=1M), it will be the proven (Sierp and Riesel) base (other than the Liskovets-Gallot conjecture, i.e. Sierp base 2 even n) with largest CK
