Based on experiments, the size ratio values approach expectation on a large scale. Lossless inputs induce lower expectations, while lossy inputs induce higher expectations. Individual images may have varied results.
The size ratio values listed below approach expectations on a large scale, based on experiments conducted on a relatively large scale with non-photographic images modelling 15.6% lossy inputs. Lossless inputs induce better (smaller) expectations, while lossy inputs tip the balance in reverse. Photograpic images will generally have a better (smaller) ratio than non-photographic images, but individual images may still have greatly varied results.
