Yep, primary they test CPU (and GPU), but also they can be used to test kernel optimisation, so thats why running this test on the same hardware, but with different firmware will show different results. In Coyote I had disabled GUI animation, so interface improovement in Dingo is allmost unnoticeable for me (but for sure it was optimised somehow )

As for closed cover test... there were an bug in old firmware which prevent EE to go in normall suspend mode. But I'll look into it later.., probably there were some changes made.

p.s. I noticed many changes in Dingo, but most of them seems to prepare for so called eDGe Junior -- next device with smaller displays and 3G module enabled.
