Not only that, but I think that Bitcoin will not accept blocks generated at a different difficulty, so if a modified Bitcoin client tried to send out more easily generated blocks, all the authentic clients would reject the fake blocks.

We need Satoshi to confirm that because clients accept blocks generated at easier difficulties all the time whenever the PoW’s difficulty increases.

The formula is based on the time it takes to generate 2016 blocks.  The difficulty is multiplied by 14/(actual days taken).  For instance, this time it took 9.4 days, so the calculation was 14/9.4 = 1.49.  Previous difficulty 2.53 * 1.49 = 3.78, a 49% increase.

I don’t know what you’re talking about accepting easier difficulties.
