Have we done the match portioit in a good way or not?

Not quite sure what "the match portion" refers to here.

We can consider it wellthink about it based on data.

We can try doing it for a week (or more than that),), see how long we can do it, and take a test to know how greatood we awere when were are doing it.

I'm assuming "see how long we can do it", is what was meant here.

Because viewing the results of the test happen after the test, it's best to talk about the test in the past tense.

"how good we were" instead of "how great we were" is because describing yourself as great can sound conceited.

Based on this data, you canould increase your intensity by 10-20% from before.

"our" is first person plural, but since the sentence started with "you", you should be consistent.

"could" rather than can here because we're talking in hypotheticals

DKeep doing it until you feel comfortable with the increased intensity.

And to improve how greatood we are doing it, we can analyze based on the results we geot when we did the test.

"got" is the past tense of "get"

You've changed from second person to first person plural here, it would sound better to keep the viewpoint consistent here.

So we will understand which sectionparts we are good at and which sectionparts we are not toohat good at.

parts is better than sections here, I think. Sections are more so used for dividing up a physical object. Parts is more generic.

If it's too hard to improve your ability in the not-so-good sections, break ithem down into smaller problems that you can repairimprove.

I changed "it" to "them" because we're talking about sections plural.

I changed "repair" to "improve" because repair carries a connotation of returning to a previous better state. If you're looking to get to a new better state, then "improve" is better.

Have we done the match portion a good way or not?

I'm not sure what you mean by "match portion" here

We can consider it well based on data.

We can try doing it for a week (or more than that), h. How long we can we do it, and t? Take a test to know how great we are when we are doing it.

This is a run-on sentence

Based on this data, youwe can increase our intensity by 10-20% from before.

Doing ithis until you feel comfortable with the increased intensity.

And to improve how greatwell we are doing it, and we can analyze based on the results we get when we didfrom the test.

You use "it" a lot you may want to be more specific

If it's too hard to improve your ability inat not-so-good sections, and break it down into smaller problems that you can repair.

rResting and lLaziness

We can consider it is done well based on data.

We can try doing it for a week (or more than that), however long we can do it, and take a test to know how greaproficient we are when we are doing it.

You can use the word great in this context, but it sounds a little pompous to me. I changed it to proficient which I think works better in a work setting.

Based on this data, you can increase our intensity by 10-20% fromcompared to before.

Doing(We/You) do it until you feel comfortable with the increased intensity.

You can start the sentence this way in speech, but it not correct in writing. There has to be a subject in here because I’m not sure who is doing it.

And to improve how great we are doing itour proficiency, we can analyze (__) based on the results we get when we dido the test.

I would specify what you analyze where I put the blank. Ex: We can analyze our performance based on the results.

So wWe will understand which sections we are good at and which sections we are (not too good/bad) at.

To sound more formal, get rid of “so” and replace “not too good” with “bad”

If it's too hard to improve your ability in not-so-goodinefficient sections, break it down into smaller problems that you can repair.

You can say “not-so-good” and people will understand but I think the word inefficient fits with what you are trying to say.
