You right. I just checked and had that issue in slic3r. I think I either just messed with the layers settings when the layers are shorter than a certain time or just dealt with the fragile tail. I found a 1.25% had at least two wide. I don't know if you have CAD software but you could get in there, trace out the skeg and thicken it a little if you want the 1% scale.
