The phrase "a consistent decrease in" is grammatically correct and can be used in written English.
Example: There has been a consistent decrease in the number of students attending the university over the past decade.
This increase was always followed by a consistent decrease in numbers with further dewatering, especially below 50% moisture.
In the lower rise, the sediment waves display a consistent decrease in wavelength with increasing water depth.
Moreover, Cu/Nb multilayer membranes show a consistent decrease in the compressive stress level with increasing layer thickness.
We have also observed a consistent decrease in specific capacitance from 260 to 50 F/g as material thickness increases.
The strains overexpressing YAP1 showed a consistent decrease in the duration of the lag phase, which lasted for 5.3 ± 0.6 hours.
The results in this work show that the addition of ethanol results in a consistent decrease in engine-out particulate proportional to ethanol content.
