My best advice ... be conservative !!! Don't use other time. Repeat, DON'T USE OTHER TIME. Check the company's website for specific guidance, some do vary. They may allow you to use a conversion factor since the USAF only calculates time from wheels up to wheels down.
If you've kept your own log, use the real PIC/SIC numbers. Make sure your PIC + SIC - OTHER = TOTAL (on the application). DO NOT USE OTHER TIME AS PIC ... EVEN IF YOU WERE THE AC. Provide your log with a copy of your SARMs product and be able to explain how and why your numbers are what they are.
I didn't keep my own log. I used 95% of the PRI time as PIC after upgrade for the C-12 and 90% for the KC-10. The rest of that time became SIC. All the other time was removed. All evaluator and instructor time was counted as PIC. I included an easy to read excel spreadsheet explaining my calculations. Not ONE interviewer ever asked me about my flight time or how I calculated it.
Think back about your flights. If you're an 80% type of guy, use 80%. If you're a 90%, use 90%. Just use what you feel comfortable with. But don't use 100% of the time after upgrade.
Be conservative. Don't use other. You can't go wrong with this. Assuming you're a heavy USAF guy, you should have plenty of time so don't worry about it. NETWORK NETWORK NETWORK. Footstomp ... NETWORK.
