Or even less, from zero to Gold in C:
TXL-HEL-TXL + 2x TXL-HEL-PEK-HEL-TXL + HEL-TXL-HEL + HEL-TLL-HEL = 20k BiS & 90,6k TP, AY+ Gold.
This is just a calculation for the least number of BiS miles to OWS.
Of course
27 HEL-TLL-HEL is just 3,5k BiS miles and AY Gold 
That is good to know, though I rarely fly C so AY will never be my main program but even as a secondary it just doesnt make much sense due to redemptions... Only upgrading seems a good deal...
Maybe one day theyll do a challenge offer then I might jump in again or just stick with one program even over the 100000 miles/points per year or credit to AS
