I think this measures are good examples how certain instruments work in real world.
In the higher register of an oboe, very short notes like staccato do have a higher volume range, because the tonal developement with staccatos are not as big compared to longer notes performing in pianissimo. Longer notes develop more tone therefor the volume is usually higher. Further performing vibrato needs more tonal stability, therefor medium long note with vibrato will be always much louder than a staccato in pp.
In ff usually a staccato note will be always louder than a sustained, the whole possible impact is produced in short amount of time. Longer notes, if they are not performed marcatissimo develop the maximum within the note. Further the tone quality is more demanding on a long note compared to a staccato, the musician has to take care that the tone "works".
Generally we take a lot of care in editing our samples, of course we can do mistakes - no question about that.
What we have is a very good reference in our dynamic samples and the dynamic repetition patches for all the mapping values.
If you need more control about dynamic ranges I strongly recommend VI PRO. Beside setting the individual volume of a certain patch in your template, you can adjust also the dynamic range of each patch individually. And at least you can setup volumegraphs on your keyboard to adjust volume for dedicated play ranges, even on single notes within a patch.
