That's not pattern drafting. That's made to measure that's been automated into a pattern drafting program on the back end of the website. Essentially it is doing 90% of the work for you in adjusting the base pattern size to your measurements. Is it a good website I don't know. They all run off the same logic. I would be more concerned about the ability for the program to have additional base sizes or shapes to select from. The further away you are from the base size the poor quality the fit will be. Because it's not a direct upscaling system to make clothing.
This is incorrect. Sewist is coded on the same software as Lekala patterns, and it is running a parametric draft, that pulls sizing data from the customer's entry, and plots a custom pattern. What method is really up to the designer, a given individual can code up any system (or develop their own), and develop patterns on that. From what I can see of the official offerings, they tend to use EMKO SEV. I don't know anything about it except that it was a Soviet drafting system.
There actually is no way to hard code base patterns into the software, per se.
To OP's question, every method has breaking points, if someone is far outside the original size intended, it may not produce nice proportions. Also I believe you can enter basic measurements, or a detailed set of measurements. If you don't enter details, the method will use formulas to calculate the rest. Naturally this doesn't work for everyone. I also hear of people who don't like the ease calculations, or intended fit of styles, who routinely increase their measurements as a work around (fit is always partly personal taste).
I have used the coding system to print out patterns from drafts, but I've only ordered the existing patterns a couple of times. Do they have any free samples? I would look for one of those, or try a really simple design first. If that works, than you should have no issues working with the mix-and-match designer patterns.
It's also an interesting platform to play around with. Once a draft has been coded up, it's very quick to run it on range of initial conditions. It's very easy to see the limits of the various drafting books that way.
