The RWR effectivety reduction is always reasonable on the "unofficial rocket mod" here:

If I recall well, we (the community) have discussed a lot about the entries to adjust to have more or less RWR effectivity on the above thread and probably also on the readme of the mod . Take a look there as I don´t recall correctly now.
Anyhow the new sh3 script with crash dive randonmization is ready, the same for verison 3 of the torpedo mod and the alternative Abandon boat mod since some time ago. i never release this package because i´m very short in free time and also because i have my doubts that if someone is using the Sh3 script (the crash dive randomization and the new Abandon mod only works with it at background). So, perhaps could be a much effort from my side for just few if any users of the mod. If someone really like and use Sh3 script , please contact me that i will provide the mod and few support on how to use it.
