MHO and Friday Hour Done – How important is the "hour" part?

I have been doing Monday Hour One and Friday Hour Done for 1.5 months. I find both processes very effective in managing my time. Can you give me some guidance on the “hour”?

If I am as thorough as lined out in the videos, MHO takes me 2-3 hours. Are there any tips for getting it down to 1 hour or is 1 hour more of a guideline?

FHD takes me about 30 minutes. This is possibly because I do an end of day check on myself daily, so Friday is really just writing down what I’ve already evaluated. I spend some time on what did not work and what I might do differently, updating my notes for next week’s MHO so the thoughts actually get incorporated.

Is there anything else I should be doing during the FHD?
