Hello, all!
I'm involved with Gen 4 romhacking and while digging through the Bug Catching contest data I found out that the encounter rates for the Gen 4 Pre-NatDex Butterfree, Beedrill, Paras, and Venonat listings are incorrect on the Wiki.
On Bulbapedia it's listed that Beedrill and Butterfree are a 5% encounter, and Paras an Venonat are a 10% encounter, but the opposite is true. Butterfree and Beedrill should be 10%, and Venonat and Paras should be 5%.
Initially I thought I was just reading the hex values wrong, but since my initial viewing the DS Rom Hacking Wiki (in cooperation with the pokeheartgold decomp project) have posted an article on editing the Bug Catching contests, which includes the above rates as I've described (I didn't have anything to do with this, I just noticed it now and figured I should go to Bulbapedia with the findings).
Below I've posted a link to said article (look for Default Encounter Set (Set 0 - Pre-National Dex)).
https://ds-pokemon-hacking.github.io/docs/generation-iv/guides/hgss-bug_catching_contests/
For further clarity (and other stuff I probably missed, since this is very much not my field of expertise) I'll also link pokeheartgold's decomp file which includes encounter rates. Those ones are read by subtracting the first value of the table from 100. In this case, Caterpie at 80, concludes that it has a 20% encounter rate, and each one below subtracts from the value above it, repeating every 10 entries. This shows Butterfree and Beedrill at 10% (40 - 30, 30 - 20) and Venonat and Paras at 5% (20 - 15, 15 - 10).

Hopefully that sheds some light on the encounter tables! And while I'm here, purely for curiosity's sake, I've been wondering where Bulbapedia got the initial rates from. I could believe it was just a typo, but one that's gone on for this long just has me itching to know. Let me know if there's any specific info/documentation needed to further corroborate this, and thank you for your time!
