Not that I am a so called experienced driver but I have come up with an easy formula for axel weights. All you need is a scale ticket or your weights from seperating your axels on a scale. I used one of my cat receipts for this and have my reweigh to verify results.
First weight steers 11,440
drives 30,420
trlr 32,880
First subtract the lower of your second two weights from the higher, in this case the drives. 30,420 subtracted from 32,880 = 2,460 now divide 2,460 by 2 = 1,230 this is the amount of weight you actully need to move. ( remember that when you move weight from one set of tandoms you add weight to the other set) now divide that weight by 225 = 5.46 (round off from 50)
this number represents the number of holes you need to slide the tandoms.
to take weight off the the trailer count back from pin, off drives count forward from pin. now use a dry erase or grease pin to mark the hole you counted off. in this case i counted back from the pin and slid the tandoms back 5 holes. I reweighed and these were what my weights were.
reweight steers 11,580
drives 31,460
trlr. 31,780
You may need to adjust the number that you use to represent the holes on the trlr as different trailers have different size holes. The trailers we use are wabash dry vans and 225 works well for our trailers.
This has taken out all the guess work for me. I still reweigh to verify my math but i have not had to adjust a second time in months. I hope this can be of use to any fellow drivers.

Don't you feel guilty not crawling under your trailer with a hammer trying to beat the slider pins loose?
What amazes me are the guys who order a trailer spec'd exactly how they want with every bell and whistle available.........but get a sliding tandem.

Only if you can't add. Who says that's the right way?
Actually kidsdad method is the same thing I've been doing for years. Once you get the system down, you don't even have to reweigh. The only time I reweigh is if I'm pushing 80,000.
The only thing different I do kidsdad is swipe my finger on the side of the dirty trailer to mark the hole. No need for a marker.
Another trick kidsdad, alot of docks you have to slide your axles back. When you pull away, put the end of that last pallet about a hole past the back axle. See how close you get then. Of course there are odd loads, but that works for most identical pallet loads that aren't nose heavy. It's a game I play.
Then again my last truck had a load pressure gauge. I scaled maybe 1-4 times a month.

Or........you could pull a spread axle trailer and never slide anything or pay to scale!
Sad thing is you could have told him you have a spread and he still wouldn't have understood and would have gave you this look!
I bet 90% of the steering wheel holders have no idea why your trailer axles are attached like that. -
