Alan is right
1k is not necessary on a good razor with proper bevel
if you spend a lot of time with the 12k, .5u and .25u it means your edge off 8k is not good enough.
the answer to your question, how to minimize honing time is actually by honing more.
lynn hones as fast and with so few strokes as he does because he has the developed the skills by honing a lot of razors.
so yeah, it's a catch-22 in a way.
