Anti-splog statistics only displayed till last detected splog


I am using Anti-Splog plugin on my WP Network and I like very much looking at the statistics page because I found the displayed information very useful.
Nevertheless, I noticed that the month activity statistics are displayed only till the last day that a splog has been detected.
That means: today, we are the 13rd of April and the stats are displayed till the 8th of April because no splog have been detected since then.
And then, I cannot have see the valuable information about how many blogs have been registered each day since the 8th of April.
Wouldn't it be possible to have stats displayed rather till current day ?
