What is the optimal frequency of 2k comps? Once per year in a venue of celebrated reputation? Four or five times in prelims or feeder competitions? How about 2k tests? The shortest Interactive 2k prep to test is 8 weeks of training. So maybe 6 opportunities per year? The longest is 26 weeks--twice yearly.
Prelims and feeders are the US route, leading the WIRC. In the Islands, appears to me that it is more a matter of lots of regional comps along with some that are mostly a matter of tradition.

I read it that far and thought, "Wow, that's one way to hit a PR, although maybe a last one." Then I got to the next line and found out that it wasn't really quite what it had seemed to be.

Saw another recent member here get a 2K PR with an initial 500m 11" faster than the next and 9" faster than the average of the final splits. Newby nonsense? Low probability of even finishing? Other time-tested strategies promise better results? Yes yes, YES!
Take note that an initial pace maintained is a FLAT pace. Somewhere someone will take this training path, succeed in competition, and everyone will swear it's the flattest-paced effort they've seen. Or the pace will go negative and everyone will swear it's down to good old time-honored training wisdom.

There seems to be two major strategies. One which is strongly favored in France, a fast first split, hang in steady for 2 splits at close to goal pace, and go negative for the last one. The other one is a continuous negative splitting, which is what Mike Caviston's extensive research appears to support. Just plain physics tells us that an absolute flat pace is the most efficient. But human psychology comes into play as well. The fast first split is very much a hangover from OTW racing, in which getting out in front at the start is considered to be a psychological advantage.
I am surprised that you used the term "good old time-honored training wisdom" for negative pacing. Until Caviston's relatively recent postings about his research on it, it was pretty much ignored - and many still disagree, as in the example of the postings about the French training, which were also quite recent.
