I'm sure 125ml rather than 126ml is fine. Afterall how did you measure the petrol volume to match up... Although fuel pump at a filling station is -0.5% to +1% accurate.
It's very complicated for no reason don't mix into part filled tanks have a spare tank a Jerry can will do do a mix in the Jerry and fill your tank from that if you don't use it stabilise for next time/season most tanks have a fill line which states how many litres fill to that and add oil

You can use these CNS Power Tools Ltd Measuring Jug For 25l Mixing (00008810182)

but mixing 10l of petrol at a time assuming 50:1 is easy (most oil bottles have 50ml graduations on the side) 200ml of oil just buy 10l of petrol and put 200ml oil in and shake.....

I just keep a box full of kids 250ml lemonade bottles in the garage pre-filled with a measured dose of oil and grab a few when needed. Full to brim (measures 270ml) does 20l petrol, 1/2 full does 10l petrol.

Quick simple easy.

75:1 (1 litre needs 14ml oil)

5 litres needs 70 ml
10 ……..…… 135 ml
15 ……..…… 200 ml
20 ……..…… 270 ml
25 ……..…… 340 ml
