his method of rescaling is the exact method you would use to rescale any antenna for any band.it's not rocket science.

although generally speaking if rebuilding an antenna from scratch for another band,
you should rescale every single dimension of the antenna including element diameters,in this case your stuck with certain diameters and rescaling distance between element spacing might not be so easy,

just changing the element lengths alone should get you pretty much in the ballpark as 27.555 isn't a million miles from 27.205. as you can see from Lorenzo's calculation the new sizing is almost 99% (98.71% to be precise) of the original size.

on another note the ros meter Lorenzo refers too is an ordinary swr meter,ros = rapport d'onde stationnaire or "ratio wave standing" from the french language.
