Phenomenon Noticed after converting Apt. outlets to screw connectors

I have the following voltmeter:
A while ago, I posted a thread about the effect of converting "back- stab" household receptacles to their side-screws, or upgrading to pressure-plate backwired outlets.
I now have three years of data indicating that my consumption(in average daily kilowatt hours) has not fluctuated much from IE: January 2005>Jan 2006>Jan 2007, etc. The biggest factor in my bills is the baseboard heat, the fridge, and the AC units in summer. Not to mention that CL&P's generation rate is now twice what it was three Januarys prior! In addition, I'm slowly converting higher wattage 75-100W bulbs(kitchen, entry way) to 15-20W(75W equiv) fluorescents.
The phenomenon mentioned in the Subject header is simple: Pre- conversion, I was getting 121-122VAC readings on the radioshack multimeter. Currently, after converting all non-switched receptacles to side-screw or back-wire, I'm now getting readings between 124-125VAC!!
Is that safe? The meter always did read a little hot(a fresh out of the sleeve AA battery would read 1.58 > 1.61 on the multimeter). Should I purchase a second multimeter and see if it returns lower/ different readings? Still, the voltage readings at the outlets are 2-3VAC higher than before all this converting went on, so I know my TVs/Stereos/Appliances are getting the most voltage they can in this apartment.

That meter has an accuracy, when new, of +/- 1.5% of fsd +/- 5 on the lsd, when on ac volts.
Assuming that you are using the 200v range, that is an accuracy worse than +/- 3v. A true voltage of 123 volts could read anything from below 120v to over 126v - so worrying about any variations in measurement within that range are pretty pointless, with this meter.
Buying a different meter is pretty pointless too, unless you buy one which has a certified accuracy better than the variations that you are trying to measure.
Don't worry about it - the voltage coming out of your sockets seems fine. Worry about something more important - like if you will actually be able to afford to use electricity in twenty years time....

Is this with the outlet loaded by a substantial load? Or with the meter and nothing else plugged into the outlet?
