A few companies do this... I know one small one that does not want to change it because it will cost too much in already printed materials. When they run out of these I'm sure they will update it.
I get it. .045, .065, .085, and .105. A few zeros missing. If they're gonna use the decimal point they should keep in mind that it's in thousandths of an inch. Took me a moment though.
I know one brand that refused to understand there was a problem with their packaging like that... I no longer carry it.
Its all good. I sometimes miss this on packaging... Just look at the 45 etc... However... Some brands just put those numbers but the actual gauges are different.
Once installed, tuned to standard E and properly intonated, I dug out the vernier callipers and took some measurements at room temperature. The actual gauges in inches are 0.047, 0.067, 0.087 and 0.106. Not bad I'd say.
It happens. Fodera and a few others have done the same thing over the last couple of years. I wouldn't avoid buying string set just because the string package was labelled .40-.100. Seems senseless to me unless the gauges are actually not .040-.100. I would also never say "give me a point zero forty string" either.
