The 980 is the number reported on the 9th, This information will come with the date the actual death occurred. So is split up and up so lets just say 117 were allocated to that day so look at the 9th on the left running total follow that along to the 9th on the top daily figure you will see the 117. Now if you go back to the 8th you will see the 140 has become 496 so some of the 980 has gone there and the 980 will be allocated all the way back for example 5 th march goes from 3 on the 8th to 4 on the 9th.
The reported figure for the 8th April has gone from 140 to 496 to 657 as each day numbers are allocated tomorrow it will increase again as will todays 115 as tomorrows reported figures are allocated.
