On a typical 10meg line, you'd be able to pull around 3.6GB of data in an hour (assuming 1MB/s throughput). That means you will effectively be paying ~R8 per GB for that hour.
However, since you've already paid for your uncapped part, the R8 per GB is false. If you can manage to download, say half of that (1.8GB) without the 'turbo' add on, you will effectively be paying ~R16 per GB for the 'turbo' add-on. Obviously the better your non turbo'd performance, the less effective (and more expensive) the turbo add-on becomes.
On a typical 1meg line:
- 360MB per hour
- R29 gets you 8 hours of Turbo
- so thats R29 / (360*8)...
- ~R10 per GB...or probably more realistic ~R20 per gb.
Worth it ?
I dont think so. Nice try though.
