I seem to be noticing a issue with my speed settings. They do not feel right to me from what I set them to, to what they actually do. It became very evident to me that something might be wrong when I changed from mm/s to % on the First Layer. I normally have my First Layer set to 15mm/s but I just changed that First Layer Speed setting to 50%. When I did that everything went twice as fast. I was thinking that 50% would be slower than 15mm/s for some of settings, well most of them. For example my Perimeters are set to 20mm/s so 50% should be 10mm/s, yet they were moving like they were about 60mm/s while it was set to 50%. This seems odd to me.
Am I missing something?
Have any of you noticed a similar issue with the Slic3R Speed Settings?
Here is a pic of my speed settings if it helps:
