There is no viable metric that dictates how many links you should or can generate in a 24 hour period. Additionally, it takes days sometimes weeks to pick them up in the first place. If they are mass produced they are useless anyway. Nigel
To be honest, I don't think there is any evidence to suggest that getting large numbers of links some days and not many links on other days will bother the Google penalty department - Otherwise, we'd all link bomb our competition, get them all kicked out leaving us in the #1 spot
just make sure they're quality links and I don't think it cares. I bet a big search engine like Google probably tracks your statistics, so when they see your website is starting to lose interest level, then they will probably lower your ranking later on.
Are you building these backlinks by commenting on blogs or through article and directory submission? As long as they're posted on different IP addresses then you're fine.
The variety of opinions on linkbuilding is pretty interesting, considering that there probably is not a hard and fast rule on link velocity or traffic generation. Moderation in everything should pay off well. If you're building backlinks for direct traffic generation from the links - and it is working - then what do you care about its short term effect on your google SERPS? Even if you get sentenced to the sandbox for building them quickly, you will still be generating traffic from them and will rebound strongly after the penalty is lifted because your Alexa ranks will be high and your bounce rate will presumably be lower than average due to the statistics associated with a large amount of traffic. If you're focused on moving up through the SERPS due to the number of your backlinks, then you shouldn't concern yourself with the poor quality traffic generated by having low PR/low traffic backlinks - your good traffic will come from your Google ranking. The most pointless thing you can do is to build tons of poor quality links that do not generate any traffic themselves and not build any direct-traffic generating links. That is why I like linkwheels - the sites that you build (ideally) generate both traffic and link juice.
