So, I just got my first set of DR Sunbeams. Bought a medium-light set (45-65-80-100) to try something else for a change. Something felt 'off' so I measured them and they came out as 40-59-73-93. I get that string sizes are not an exact number, but that's a noticeable difference and measures more like the Sunbeams light (40-60-75-95). I'll contact the seller, but first wanted to double-check if this is to be expected from DR Sunbeams...
