Reduce number of panel units for mapping double-curved surface

just got some clue about my own question lol
So planar panelization using Paneling Tools is a trade off-deviation value vs accuracy maintaining the original form. This is my undertanding so far…

I just got the result from another Paneling Tools test, although this time i set UV both as they are reality (way bigger than my first test), it generates all panels, only most of the panels are traingles, looking like loft got different directions lol

Before i use the doubly-curved srf to test, i dupborder and rebuilt two edges then loft, so the new srf gets smaller. Then i took the above 2 steps in PT and about 2hr here shows the results. Not sure how to improve my steps… If we could get all panels to be planar quads that would be fantastic!
