Interesting chart, it suggests rate of decay is size/mass dependent. RAIKO which is a 2U CubeSat and was deployed 2nd is now higher than all the others.

I'm ploting altitude of five CubeSats which were deployed from ISS. The results is interesting. First deployment satellites are lower altitude than laters. I guess this is related to initial velocity at deployment.
First Deployment deployment order: #1 WE WISH, #2 RAIKO altitude: WE WISH < RAIKO
Second Deployment deployment order: #1 TechEdSat, #2 F1, #3 FITSAT-1 altitude: TechEdSat < F1 < FITSAT-1
I'm also ploating ARISSat-1 on the same chart as its time line align to the five CubeSats deployment date. The chart shows five CubeSats have large decay rate than ARISSat-1.
You can see the chart on the following URL.
