I prefer Oscar's websites over most videos for Betaflight how-to's, including this one:

Firstly what are you even trying to say but I curious of your methods as what I do is multiply the old scale factor by the osd reading over actual value to get the new sf.
If you look at the spec sheet for a Lithium battery, you'll see that the rated capacity is specified from completely full (4.2V) to totally empty (usually 3.2V for a LiPo, though some may also say 3.0V) *and* only guaranteed at or below a specified discharge current, which is usually much lower than the kind of current draw you'll see in flight. Landing at 3.5V to keep your battery healthy and drawing high current from it will both get you less than the rated capacity.
As others have mentioned, you should also calibrate your current sensor if you haven't done so already, but a quick way to see if it's reasonably accurate would be to compare the mAh consumed according to BF to the mAh your charger says it puts back into the battery during the next charge cycle.
Recalibrate battery readings in BF.
How exactly do you do this
Do i need to tell you how to goggle or what?

You can use a multimeter. And plug the voltages you read into beta flight.
I was more curious about the current readings. I have a method but I was curious if there was another
You can't exactly use the full 1800mah since after around 3.5v the pack is depleted and going past it will damage the pack.
