[Wien] [Wien2k] Fermi Energy in case.in1 file

[Ghosh SUDDHASATTWA]

My current system is having a space group no 194 
[SuddhasattwaGhosh] 
The SCF cycle converges for 12000 k-points with APW+lo with rkmax 8.00, 8,5,
9.00, 9.5 and 10.0 
The Fermi energy in the .scf2 file changes from 0.67 to 0.70 in case of
rkmax of 10.00 (Emax is 2.5) 
I guess rkmax is quite good as well as the number of k-points. 
Can anybody suggest if still I have to increase rkmax to improve the
accuracy
