Well, I'm assuming that you had you swaybars disconnected when you took the readings.

F to R looks pretty good.
Since the total F to R is 50.2%, then the left and right sides, each must also have the same distribution for the weights to be ideal.

The good news is that by my quick look at it, you are about 30 pounds low on the RF & LR,,,,,and 30 pounds high on the LF & RR.

I "rounded" to the nearest pound, and here is what I calculated your ideal corner weights should be,,,,according to the 50.2 front /49.7 rear total distribution you posted.

RF ideal weight= % on front tires X total weight on both right tires, divided by 100 (50.2 X 1417)/100= 711 pounds


LF ideal weight= % on front X total left, divide 100,
(50.2 X 1408)/100 = 707 pounds

RR ideal = % on rear X total right, divide 100,
(49.7 X1417)/100= 704 pounds

LR ideal= % on rear X total left, divide 100,
(49.7 X 1408)/100 = 700 pounds

For a great set up, you want to be within 10 pounds of the ideal weight.......
You are at around 30 off per corner, so you aren't too far off.

Remember, to increase the weight on a tire, you raise the ride height on it,,,,,,,,,,,,and to decrease the weight you lower it.

The fun is that any change in one corner will affect all four.
Usually you try to make a 1/4 adjustment on each corner to get your goal. ....which means you want to make roughly a 7-8 pound increase at the RF and LR,,,,,,,,,and a decrease in the LF and RR.

I hope this helps. I just dug up some of last years "note's" from my racecar and stuck in your numbers,,,,,,,,so I think I have you headed in the right direction.

I'm sure if I spewed & got it all wrong,,,,,,,,one of the chassis guru guys will be happy to point it out.
