Thanks freemangordon, now i understand what it is going about. In situation, where we're close to optimal values, I always prefer a little "too high" voltage, than one "tiny-bit too low", even if it may appear only during certain, specific situations - but, AIUI, You're trying to achieve exactly same thing, 100% safe values, that are - at the same time - saving battery. The idea is very appealing - I wonder, how up times on one battery will look with dual-scud 3000 mAh I'm using

Only one small question remain - do you think that - with new values - current idea of "race-to-idle" (i.e, that limits 500-900, are more power-efficient that 250-900 or 1250-900, due to device finishing tasks faster on 500-900, and setting on 0 for more time), are outdated with new Sr, i.e 125-900 is now more power-efficient (or will be, after finalizing SR vdd2 also)? "Common sense" still tells me, that it's better to finish task on 500 mhz, and sit on 0 mhz (saving on power leakage), than doing it longer on 125 mhz, even extra-low-voltaged. but, I may miss something, that's why I'm asking.
