There will be three compounds at each race, as expected with the simplified hard, medium and soft names. The FIA characterises the tyres as follows:

- Hard compound: 2s degradation achieved at 22% race distance Base lap time

- Medium compound: 2s degradation achieved at 18% race distance 1.2s/lap quicker than Hard compound

- Soft compound: 2s degradation achieved at 10% race distance 2.2s/lap quicker than Hard compound

I assume something like this was written into the current tender and contract which Pirelli are fulfilling so you can't blame them for the state of the tyres - just the requirements of the contract.
Ignoring the badly worded:

"Once a period of aggressive driving or close following ceases, the tyre should rapidly recover the lower level of degradation per lap associated with the more benign conditions."

Once overheated, the Pirelli's never recover grip or wear!
