There are some lovely doilies in Endrucks' book, all worked in one pass. What I find, though, is that unlike her straight lace patterns, the circular doilies tend to either ruffle or cup, and some tweaking of count is required. I think it is a matter of individual tatting tension?
Above I have traced the 'modern' path of climbing out of rounds (in blue). For this to work smoothly, I had to work a couple of rounds counterclockwise. The orange path shows how Frau Endrucks moved to the next round - simply add another chain(s) till you reach the point where you can climb out!
UPDATE: I have coined the term 'SHADOW CHAIN' for this extra chain(s) used to climb out to the next round, row, or motif, thus enabling continuous tatting.

UPDATE: Pattern for this doily is uploaded, showing both methods of climbing out - https://drive.google.com/file/d/1vG2g0JCVsy8cy2DfGKHEhxleq_7Rveba/view
Since the first few rounds can be worked off a shuttle and ball, I used my earlier tip about extending the thread between 2 shuttles. All the extra thread in left pic was wound on to the ball temporarily, till it got used up and the 2nd shuttle was needed.
Of course, one can simply keep shuttle 1 and ball thread continuous and tat till the 2nd shuttle is needed. At that point, pull out the length required, cut from ball, and wind up shuttle2.
There was a lot of ruffling in the green model, despite adding a few stitches to a later round. So I started another in tinted Anchor size 20, with modified stitch count. Worked beautifully and lay flat. The 3rd round does ruffle till the 4th round is added, but this is a structural problem.
Ran out of thread after 5 rounds, hence added a bold violet shade to add a spot of colour. I kinda like it - what do you think?
I am busy with pattern #17, hence this pattern pdf will have to wait a bit. However, for those who'd like to try it right away, you can find the written instructions and tips by Georgia here.This is Pattern #28 from Schiffchen-Spitzen 1920 by Eleonore Endrucks-Leichtenstern. You can find all the links in the Endrucks 1920 Project doc here along with all other patterns in modern format. We are hoping to have all of Endrucks' patterns in modern format by this November - a year from when we started.
