solder mask defined pads. On the plus side, GND floods would have much better connectivity without thermal relief, especially in cases where you are reduced to 1 or 2 spokes due to other routing near the pad

. IPC uses the Pad Size to calculate Thermal Relief and Proportional uses the Anti-pad to calculate the Thermal Relief. The big difference is that the Anti-pad is a much more stable number because it's calculated by the hole size which is always consistent
