"100% Improvement"

Is this even possible.

I've had an email from Symantec about upgrading one of their products to the latest version, Backup Exec 2014. They claim up to 100% speed improvement in backup times.

So a backup that used to take 2 hours, will now potentially take no time at all, literally?

I'm sold.

i dont think you get it. 100% better just means twice as good. and with symantec they probably just mean 'a bit less sh*t' or 'almost works now'

A speed increase of 100% will make it take half the time to complete :p
The email came in early this morning and I read it 20 times, being sure I was wrong (not what I wrote in the OP)... it's been one of those months - match sticks wouldn't suffice in keeping my eyes open at the moment!

One part of my brain was saying:

100% of 2 hours = 2 hours
2 hours - 2 hours = 0

What a bellend :blush:

I was once asked to look into why a bonus scheme a company had introduced wasn't working. It turned out they'd set the normal level working at 100%, usually it's 80% and bonus is paid for anything above normal. Setting it at 100% meant workers had to achieve 101% before they got the bonus payment which is impossible.

I think it depends on how the improvement is being measured.
i.e. if it used to take 2 hours to update and now it takes 1 hours, to me that's a 50% improvement. However, if we say the upload rate was 1mb/s and now it's 2mb/s, that's a 100% improvement.

Ofcourse, in a marketing sense a 100% sounds better.

2 hours to 1 hour is a 50% reduction in update duration, or a 100% increase in update speed (n/2 per hour to n per hour)

100% 'improvement' is a bit of a sloppy term IMO

Yep, I had a look at their website which actually states in the specs. 100% faster backup speed. Which I'd say is technically correct and comes with a disclamer [*based on our internal testing]. The email is is probably written by 'non-techies', unlike the specs.

Its all psychology really, people are drawn in by A: large numbers and B: getting more for their money. ergo focus groups(in marketing studies in general) would test more positively to a 100% Increase in performance over a 50% reduction in time. even though they are the same thing in reality.

agreed. you can bend stats to your desire a lot of the time.

and knowing symantec they probably tested an old pentium machine with IDE HDD over a sata 3 xenon server. they are a terrible company.
