Hi all.

Peak: 60GB
Off peak: 330GB

Peak Usage Period is 8.00am until 9.59pm Monday to Friday
Off-Peak Usage Period is 10.00pm until 7.59am Monday to Friday and All-Day Weekends.

Anyone good at maths lol

Peak = 320Kbs

Off Peak = 2.5Mbps

Ish

really? thats a lot higher than i expected

That looks way too high.

Checked y conversions and looks OK

Assume 30 days in a month and 24 hours a day (!), splitting according to peak/off peak

P = 30 * 14 = 420hrs
OP = 30 * 10 = 300hrs

Peak-> 60GB in 420 hrs = 0.142 GB/hr = 3.96X10-5GB/sec=332Kb/s (kilobits)

OP-> 330GB in 300hrs = 1.1Gb/hrs = 3.06X10-4GB/sec = 2563Kb/s

Just the off peak is 305.5' kb

argh... i'm all confused now.

Ok so what's your working? - you're a factor of 5 out from me - I just want to know where I am wrong (if I am)

ok, I definitely get 56KB/s and 312KB/s based on March.

there's 22 Weekdays so 22*14=308hours peak

and 22*10 + 9*24 = 436hours off peak

60/308 *1024^2 /60^2 = 56KB/s

330/436 * 1024^2 /60^2 = 312KB/s

... now for my "Methods of Applied Maths" project

Thats right mate, I just didn't bother with the 1024 did it as 1000.

my fair usage policy is something like 20GB in peak times (4pm - midnight) and as much as I like offpeak. but I only get 2Mbps. and they seem to throttle usenet to about 10KB/s during the day (something like 10-10) so it's rubbish, I don't think I could break the fair usage if I tried.

Used to get around the Usenet throttle by going through Uni VPN but i can't get vpn to work in vista

i get 250KB/s all night though, so it's not too bad i suppose.

Is this an Enta or Enta re-seller package?

You might need to account for that. Just a thought.

Ah, misread peak / off peak times that’s why. But we’re in agreement as to method. – BTW I was working in kilobits not kilobytes as that is what d/l speed is quoted in. Dropped the hrs into my spreadsheet I get 454Kb (56KB) Peak and 1763 Kb (220KB)

Yeah looks like an Enta package which does include upload, im on UKFSN's 60gb peak, 330 off-peak package, and im no where near 60gb yet in peak hrs, only done about 11gb, and theres only just over a week left of this month, my total bandwidth which is peak/off peak alltogether is only about 30gb, if your worried about going over yer limits you must be doing some serious downloading.

depends on the program you use I guess - most things I use (newsleecher mainly) give KB/s

1000 is the proper usage anyway not 1024 as kilo means 10^3.

Not in computer terms it doesn't

The SI standard is 10^3 and that is what should be used and is what hardware manufacturers use, 1024 bytes is a kibibyte 2^10.

1000 bytes in a kilobyte is the standard for networking and computer storage media.

1024 bytes in a kilobyte is a convieniant way of measuring ram because it is in base 2 binary, the si standard should still be used though.
