Ok, here are my thoughts. Use them as you see fit. I'm not MIKE, only a student of his.
Man Power: 516,676 (Don't think I have to worry about this ever running out)
Heavy Industry: 174,300 (I think this is a bit low - what do you guys think ?)
Armaments: 99,410 (I am aiming for 100k stockpile)
Naval Shipyard: 24,924 (Thinking about turning these off for a few turns to use up the stockpile)
Merchant Shipyard: 10,404 (Slowly decreasing due to accelerating of TKs)
Vehicle: 5,071 (Was at 10k but I have upgraded a lot of armor recently)
Armaments - take a look at the curves in tracker ... you get a lot of reinforcements beginning in '43 that will eat up a lot of Armament (and Manpower). If you haven't increased this, then you will likely need to let it build until '45. Meaning, you will in mid '43 have what appears to be a HUGE stockpile.
NSY: did you accelerate all of the Unyo's? Unless you have expanded your NSY greatly, generally you don't have much excess.
VEH - never seem to have enough, but you can't expand everything.
(Actual factories not stockpile)
Man Power: 850
Heavy Industry: 7106
Light Industry: 9944
Naval Shipyards: 1402
Merchant Shipyards: 827
Aircraft Engines: 825 (See below)
Aircraft: 817 (See below)
So you've expanded NSY, VEH, and AC/ENG. Have you had bad luck on capturing HI? Can't recall now from your AAR. I'll go back and read.
All available Engine factories are producing and several new ones come available in a couple months.
Not all factories are producing - I try to maintain a certain level in the pools and turn factories on/off to conserve both HI and Engines for later models.

I also have 2 factories that I haven't decided what to build with yet so they are turned off and sitting idle.
Any comments / Questions ?
You shouldn't need either of the Ha-31 or Ha-5 by this time. You should have big enough pools. Can't recall if you are PDU ON or OFF. Looks like PDU OFF.
Still, if you haven't started building Ha-34 for your Tojo/Helens, you are late. Get at least two engine factories converted, more likely at this late date you will need 4. If you're going to produce 100xTojo and 100xHelen, that's 300xHa-34 you gotta make. That makes it your biggest mid-game engine factory complex until you shift to the Ha-45. Even with PDU OFF, a large portion of your fighters can upgrade to Tojo and same for your bomber groups to Helen. Tracker will be able to tell you exactly.
While your investment in the Ha-34 is huge, the good news is that Helen remains about your best IJA bomber until the end game. You may wish a few Peggy for the torp, but that is up to you. Tojo will get replaced by the Frank, but not for another 18 months.
I would start to plan your conversion to the later models now. How/when will you start to convert to the Ha-45? What your kami model will be and which engine will it use? EX; if you use the Toka/Tsurugi then you need to keep you Ha-35 factories idle until '45. However, if you decide that you will use Grace, then you are going to need to convert those engine factories all to Ha-45. Lot's of ways to go here, and I don't think there have been a "best way" proven yet. But if you plan it out now, you can minimize that expense. Converting factories eats up a lot of supply and HI. don't want to do that more than you have to.
