Percentage increases are really worthless when you think about it. If one person starts a company and goes from having 1 customer who spends $10 a month to 5 customers who spend $20 a month that is good and the growth is amazing. Customers went up 500% and revenue went up 1000%. I'd certainly call that pretty good. However, a bigger company can go from having 100,000 customers paying $40 a month to having 110,000 customers paying $42 a month. There's not that much growth there if you're just looking at percentages but I'd take the latter over the former in a heartbeat.
Remember folks, just because there's a good percentage growth doesn't mean that its really all that amazing.
