This is a distraction from the topic but let's get it out the way.
If naturalistic processes cannot likely produce something like Cytochrome C, then they cannot produce any pattern of sequences of it either.
The number of sequences that will produce something 'good enough' is orders of magnitude greater than the - astonishingly massive - number of sequences that result in the optimum version.
It arrives at its final form as a result of natural selection that favours any small improvement. After that, any future changes will be selected for if and only if they don't negatively affect the efficiency of its function.
The calculations by Yockey were not just for optimum sequences but for all possible functional sequences.
So unless you have another source demonstrating better odds the evolutionist problem is still there.
