Adicionalmente, determinados elementos del inmovilizado material se amortizan de acuerdo con un criterio degresivo basado en coeficientes constantes, por entender que la depreciación real experimentada por estos bienes, en base a criterios técnico-económicos, se adecua mejor a este sistema de amortización

Additionally, certain tangible fixed assets are depreciated by the declining balance method based on constant coefficients, because in technical and economic terms, this depreciation system is understood to more adequately depict the actual depreciation of these items.

Keeping in mind, that the accepted translation for criterio degresivo is by the declining balance method, I would appreciate any ideas to make this sentence sound better.
