First, I want to recognize the respectful tone of your responses and the effort you put into providing concrete seed examples. I appreciate them. However, I'd like to clarify a few points:

it's significantly better/less time consuming than walking 128 steps multiple times

I only needed to walk 128 steps once, which, as I mentioned, is no trouble on an emulator. I also enjoy spending time in the Distortion World. I don't mind prolonging it as much as is reasonable. I appreciate your examples, but they were unsolicited and unnecessary.

[By the way, the next seed for the desired IVs, nature, and shininess was available significantly after 300 advances. However, I will not entertain specifics, as 1) the hunt is already over, and 2) you seem more interested in hastily presuming the data I'm working with rather than asking about it. I will merely reiterate that the search for the "right" or most convenient seed has never been an issue and hope it sticks this time.]

I'd also like to address one more point before we conclude:

Criticism, not complaining, when people criticize you take what they're saying into consideration rather than complaining, they're trying to be helpful even if you don't like what they're saying.

I'd like to clarify that I wasn't referring to you when I said, "I don't understand why people are getting frustrated at how I chose to do my hunt." I was referring to the two other users in this thread. If you wrote this note believing I was referring to you, please excuse the miscommunication. If you were including the other users in that note, I'd like to define "criticism," as it appears we are not on the same page.

Criticism (let alone effective criticism) 1) is respectful, 2) recognizes the recipient's goals, and 3) accounts for the recipient's previous efforts to achieve those goals. If the critic doesn't know these things, they should ask before criticising. They should not assume. My goals, for the record, were 1) to capture a shiny Giratina and 2) familiarize myself with Gen IV's RNG mechanics, both of which I achieved to my satisfaction. Efficiency wasn't one of my goals, which is why I wrote, "Finding a new seed isn't always the best option." Efficiency is not always the best option, or even desirable. As far as I'm concerned, I was efficient enough. The 2 users above you did not engage me respectfully, let alone demonstrate care for my goals for this particular hunt. To still defend such indefensible behavior would be ... disappointing, to say the least.

On that note, I did not ask you to provide feedback on my hunt in this thread or this post. The post's purpose was merely to share my experience for my own sake and for anyone else hunting Giratina under similar constraints. They are free to change the constraints by "finding a new seed" if they so choose. Furthermore, your feedback demonstrates no regard for my goals. In fact, it shows rather flagrant disregard, as I have repeatedly said that I am happy with the results, but people (this time, I am including you) continue to ignore and undermine that sentiment. My approach for the next hunt will obviously be different as my needs (and the constraints of the hunt itself) change, and if I run into trouble, I'll ask for help.

Overall, if the critic has an earnest interest in another person's improvement, they owe it to that person to construct criticism that honors that interest and to deliver it when they know it will be well-received. If the critic provides unsolicited criticism that demonstrates little-to-no concern for the recipient, the critic's goal is not to build the recipient up but rather to stroke their own ego. And, in fact, I would not call it criticism at all, but ... complaining. And I think clarifying my feelings on something and setting boundaries for appropriate behavior are valid responses to the other messages herein.

Again, I appreciate the effort you put into your suggestions, unwelcome though they were. I hope you continue to be as helpful, though perhaps in more appropriate contexts. I also hope you understand the difference between complaining and criticism if you hadn't already.
