The bigger principle to consider though might be how much your "slowing" actually matters. Chances are that being slower for a few hands (even if just before the money bubble) probably won't get you too much further - maybe one spot if you are lucky.
But the whole point is, that sometimes making a few places further makes a lot of difference to your result, while other times it makes no difference. Lets just take as example one of the tournaments, that ran on
888 Poker yesterday, the 8,8$ "Voyage", which began at 5 pm CET.
This saw 262 unique entries and 83 reentrys for a total price pool of $2.760. 48 players got paid, so making it all the way from 262. place (ignoring the reentrys) to 49. place gave absolutely nothing, even though it took more than 4 hours, since this is a slow tournament. However making it from 49. to 48. place resulted in a price of 19,59$, so it should be kind of obvious, that its not very good to finish in 49. place and also not in the next places like 50., 51., 52. etc.
Actually when it was down to 48 players in this tournament, 940,32$ were already distributed, which is 34% of the price pool. So from that point on players were only competing for the last 66%, which mean, that the value of each chip went down tremendously. It should also be obvious, that if our goal is to win money in tournaments, we absolutely can not afford to not care about getting the largest possible share of 34% of the price pool.
Whats even more interesting is, that the 16. place finisher only got 21,8$, so making it several places further after the bubble meant almost nothing to his result. Only the top 12 finishers got significantly more than their initial min-cash with the winner taking down 559,68$. So it makes a ton of sense to do quite a lot to make it into the money, and only then start to gamble, so you give yourself a chance of winning the big prices like the 559,68$ first price.
More reliable would be taking really long from the beginning of the tournament - that would slow down your table somewhat
That would make no sense, since once again there is no reward for outlasting the majority of the field, unless you make it into the money. To win money in tournaments, you do need to accumulate chips. You just dont need to dust them away taking unnessesary risks, when only a few more players need to bust, before (in my example) 34% of the price pool is already distributed
