How to arrange the weight numbers in a superfamily

I have superfamily fonts that contain weights less than Thin=100 and are thicker than Black=900
and I do not know how to arrange and name weights!
How can I do it right? Please

The weight value must stay in the 1–1000 range (inclusive). Names are arbitrary, but the OpenType specification has some recommendations. You can have a look at other font families with extreme thin and bold weights for inspiration. Hairline or Ultra Heavy come to mind. Or use Heavy for 900 and Black for 1000.


Thank you
In this way, I divided the weights between 10 and 1000 and added custom names.
If there is a problem with use, I will write here.
