@Alan sorry for my late reply. While the 'black line' as the graphical representation updates automatically when you remove a cycle (either as mean or median, whichever you chose) it it not possible to update the plain decay number in an easy way. But having both, the decay over the last 4 and the last 8 cycles will hopefully help in getting some 'grip' on the actual behaviour (will hiwever note it for possible future engancements)
