Seen-over-capacity fractions cite their lattice source. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Half the sourced capacity is seen
Raw hits 6 split into seen 4 and masked 2. The sourced capacity is 8.
o=4/8=1/2
Seven of ten channels are seen
Raw hits 9 split into seen 7 and masked 2. The sourced capacity is 10.
o=7/10=7/10
Three quarters of capacity is seen
Raw hits 12 split into seen 9 and masked 3. The sourced capacity is 12.
