+# Scores Legend
+
+4 : Clearly major background for most of the PAGs, for sure need to do ASAP
+
+3 : Clearly major background for most of the PAGs, for sure need to do, but needs some time to think about modeling of the MC samples 
+
+2 : Possible to do but needs some time to think about modeling of the MC samples (+ have other samples with different generator or binnings as alternatives in block 3 or 4) 
+
+1 : Possible to do but needs some extensive time to think about modeling of the MC samples
+
+0 : Modeling of the MC samples is too delicate to be handled by non-actual-analyzers or have relatively smaller cross sections compare to other processes in the list.
+
+# Preparation Status
+
+null : Nothing yet
+
+gridpack : Initiated gridpack production
+
+preparing : Gridpack done, awaiting McM validation
+
+submitted : Submitted with full chain
