bufferT1Before = input.int(180, "Tier 1 Buffer Before (min)")
bufferT1After = input.int(180, "Tier 1 Buffer After (min)")
bufferT2Before = input.int(120, "Tier 2 Buffer Before (min)")
bufferT2After = input.int(120, "Tier 2 Buffer After (min)")
bufferWBefore = input.int(180, "Weekend Buffer Before (min)")
bufferWAfter = input.int(180, "Weekend Buffer After (min)")
