Is this statement construction correct?
"I do understand [w], [x] and [y] much better than I do [z]."
I just wanted to know if this statement is correctly constructed. Here w, x, y and z variables are plurals. Suggest me better options.

Although it's constructed correctly, the repetition of the I do phrase is somewhat unnatural.
The following would be better alternatives:
I understand [w], [x] and [y] much better than I understand [z].
There is no real reason to use do in either location here.
I understand [w], [x] and [y] much better than
I understand[z].
→ I understand [w], [x] and [y] much better than [z].
You can also remove the repetition of I understand; the sentence will remain understandable because of its parallel construction.
I do understand [w], [x] and [y] much better than
I do understand[z].
→ I do understand [w], [x] and [y] much better than [z].
Here, the first do is used, but also emphasized. It could be said in response to somebody who says you don't understand [w], [x], and [y], where the negation of their statement is emphasized.
Finally, there is another version that could be used:
I
dounderstand [w], [x] and [y] much better than I dounderstand[z].
→ I understand [w], [x] and [y] much better than I do [z].
Here, in an odd use of parallelism and elision, one of the words is omitted from the first part of the sentence, while a different word is omitted from the second part of the sentence.
Normally this doesn't happen. I can't explain why it's done in this case, aside from just saying it is, and it sounds natural because of that.
In summary, the original sentence is constructed correctly, but it's not completely idiomatic:
? I do understand [w], [x] and [y] much better than I do [z].
The following are all more natural sounding versions:
✔ I understand [w], [x] and [y] much better than I understand [z].
✔ I understand [w], [x] and [y] much better than [z].
✔ I do understand [w], [x] and [y] much better than [z].
✔ I understand [w], [x] and [y] much better than I do [z].
Which of those should actually be used is a matter of personal opinion.
