Shinpachi that is simply brilliant work my friend, well done.
For your consideration,
Can I add that the latest research in Japan is now leaning towards the Sentai marking for Yoshida's aircraft being Red, as it is now believed that he commanded the 1st Chutai (Red marking) rather than the 3rd (Yellow).
I have reviewed the best photo of Yoshida's Ki44 with the 6 victories and the Sentai marking very closely matches the fuselage Hinomaru in tonal value. I found another image in which 1st and 3rd markings are visible and the yellow appears much lighter in comparrison to the red marked aircraft.
