Really depends on your extraction pipe flexibility is getting the access to the bottom of the bearing housing.
See what adjusting, repositioning the extraction pipe makes first, and then progress to the repositioning of the Car. Slope, Tilt, Front High or Low to increase the quantity extracted and the end results.

1 oz= 28.4ml
3 oz= 85.2ml

I think I'll do it level as that's what most other people are going to do, and I'm trying to run this test under real-world conditions.

Thanks again for the tips and ideas, I'll let you know the results

Here is a chart from Eaton on oil fill capacity.
Does not mention the Jaguar R1320 specifically?

Yes saw that and asked Eaton for clarification for the TVS 1320. Heard Zip back.

These below are TVS R 4 lobes rotor.

4.2 fl oz R1320 and 5.1 fl oz R1900

These below are TVS 3 lobe rotors.

5.1fl oz TVS 1900

It would make sense the smaller Supercharger TVS 1320 has less oil, 4.2fl oz. (or 4.1fl oz) as the TVS 1900 has 5.1fl oz.
Even thou a lot of people fill the TVS 1320 with 5.1fl oz.

The difference between the TVS and the R is the number of lobes.

TVS R1900

TVS R1320

US fl oz= ml.
4.2fl oz = 124.2ml
5.1fl oz = 150.83ml

So if loss rate is 125-87ml = 38ml over 65k km = 5.85ml/10k km.

So what is the effect of adding 150ml of oil to the TVS 1320?

None so far as I know!, but gives you 25ml more oil and 40.2K km before reaching 87ml in the bearing housing. If the seepage loss remains the same.
