The phrase "an even more precise" is correct and usable in written English.
It can be used when comparing the precision of something to another, indicating a higher level of accuracy.
Example: "The new model provides an even more precise measurement than its predecessor."
Alternatives: "a more accurate" or "a significantly clearer".
The spacing had been about five days, she added, and Judge Castel indicated that he wanted an even more precise time.
The Greeks, in turn, discovered the Callippic cycle, which consisted of four Metonic cycles minus one day, and was an even more precise way to reconcile the cycles of the sun and the moon.
It was moved from Brookhaven, where the most precise measurement so far was made, to Fermilab, because Fermilab has more intense sources of muons, and so an even more precise measurement can be made there.
We need to produce long-term SROI evaluations by continuing to gather data focussed on putting an even more precise social and economic value on sustained recovery from alcoholism.
In the late 13th century, St. Nicephorus the Hesychast produced an even more precise "method of prayer," advising novices to fix their eyes during prayer on the "middle of the body," in order to achieve a more total attention, and to "attach the prayer to their breathing".
We are using an even more precise metric the savings of energy, as a percentage, when the lattice is stored on-chip, rather than onto the external DRAM.
So, in order to create an even more accurate model for the more precise prediction of the deformation over time, we believe that the material characteristics should be investigated globally on site using non-destructive testing, i.e. in a large number of positions, on the warship.
You could also try out a timer for even more precise time-keeping, especially if you are preparing for a timed exam like the SAT or ACT.
In addition, ongoing progress in ultra-sequencing technologies has eased and expanded the possibilities to perform measurements of millions of molecules in a single assay, allowing for even more precise modeling.
Weeden's passes became even more precise against a worn-down Aggies defense that seemingly guessed wrong on every play.
That's because their whiskers have evolved to give them a detailed sense of their surroundings, even more precise than in animals such as cats and dogs.
