I don't know if people are still having issues with MKM-001 Verbs and 2.4x speed, but I have a possible solution for a better second layer. At first I was using these settings:
EEprom Utility: Hyper Tuning "ON", Smartburn "ON", Over Speed "ON", Online Hyper Tuning "ON"
IMGBurn Setup: OPC "OFF", 2.4x
After only 1 out of 3 or 4 good burns, I decided to change it up to get a better second layer. The first layer was perfect, but the second always went high. PI max of 200+ and averages of 40-60 range. Not good. So I played around and made a few coasters to come up with these settings for the MKM-001 Verbs:
EEprom Utility: Hyper Tuning "OFF", Smartburn "ON", Over Speed "ON", Online Hyper Tuning "OFF"
IMGBurn Setup: OPC "ON", 4x (I also clear OPC in IMGburn advanced section before each burn....not sure if it helps though)
Now I got three successful burns in a row, going for #4 as I write this (not on the same PC of course). I also don't touch the PC when it is burning and shut down any and all apps that are running. The isos are on a separate HDD also.
I have three Modern Warfare 3 coasters using the old settings, but after the final settings change, it passed KPRobe on the first burn, well I got one read of 11 PIF on MW3, but its on the layer break so I'm hoping its fine. Kind of odd how burning at 4x is better than at 2.4x, but it worked for me. Maybe for you as well. I forgot to save my new MW3 KPRobe, but I can post the pics when this burn is done and I can run the disc in KPRobe again.
Here is the old burn with all settings enabled and 2.4x:
