Intermediate (and other) levels

To the team: I wonder if there is some way to rank the levels more accurately? I can't be the only one who has noticed how they have changed. The new intermediate levels are about right for me, but the older ones are at an elementary standard, if that. Are the older upper intermediate more akin to the recent intermediate levels, and is there some way to mark them so that I can tell which ones to try without opening each pdf one by one?

A quick glance at lesson: 1688 (take some medicine) compared to 2079 (fight on a plane - great lesson btw) makes it hard to see how these can be considered the same level...

Would be glad to hear what others think on this...right now I'm working through some of the Qing Wens, as I feel like theres nothing for me to study at an intermediate level... what should I do? make the jump to upper and start at older lessons, on the assumption that they will be easier than recent intermediate lessons anyway?
