let's fix that weird 18–20 text. When you copied the code, Google Sheets didn't like the long dash (–) and corrupted the text.
Go into your buildLineCenteredBuckets function and replace all the long dashes with standard keyboard hyphens (-).
Change this: label: (anchor - 6) + "–" + (anchor - 4)
To this: label: (anchor - 6) + "-" + (anchor - 4)
Do that for all the labels, and it will print perfectly clean.
Now, here is exactly how to read what the script is telling you. This new output visualizes the Bimodal Distribution (the "two peaks" of a tennis match) we talked about earlier.

I love that idea. If you’re building an automated dashboard, having the script write out that exact plain-English "goldmine" breakdown will instantly tell you the story of the match without forcing you to manually calculate the percentages in your head.
We can inject a script that automatically reads those buckets, groups them into UNDER and OVER, applies those exact labels ("Blowouts", "Standard 3-setters", "Marathons"), and then spits out an alert sentence if the Marathon or Blowout tails get too high.
Here is exactly how to add that custom description block to your script.
Step 1: Add the Description Generator
Scroll down to the very bottom of your script (where you just pasted the three new helper functions). Add this new function right below them:
function generateHistogramDescription(gamesList, buckets, lineTot) {
if (!gamesList || !gamesList.length || !buckets || buckets.length < 6) return [];

var counts = [0,0,0,0,0,0];
for (var i = 0; i < gamesList.length; i++) {
var g = Math.round(gamesList[i]);
for (var b = 0; b < buckets.length; b++) {
if (g >= buckets[b].lo && g <= buckets[b].hi) { counts[b]++; break; }
}
}

var p0 = (counts[0] / gamesList.length) * 100;
var p1 = (counts[1] / gamesList.length) * 100;
var p2 = (counts[2] / gamesList.length) * 100;
var p3 = (counts[3] / gamesList.length) * 100;
var p4 = (counts[4] / gamesList.length) * 100;
var p5 = (counts[5] / gamesList.length) * 100;

var underPct = p0 + p1;
var overPct = p2 + p3 + p4 + p5;

var desc = [];
desc.push(" [HISTOGRAM BREAKDOWN] The simulation drops all 12,000 runs into buckets around the " + lineTot + " line:");
desc.push(" 📉 UNDER " + lineTot + " Scenarios (" + underPct.toFixed(1) + "% of the time):");
desc.push(" • " + buckets[0].label + ": " + p0.toFixed(1) + "% (Blowouts)");
desc.push(" • " + buckets[1].label + ": " + p1.toFixed(1) + "% (Standard 2-setters)");
desc.push(" 📈 OVER " + lineTot + " Scenarios (" + overPct.toFixed(1) + "% of the time):");
desc.push(" • " + buckets[2].label + ": " + p2.toFixed(1) + "% (Long 2-setters or fast 3-setters)");
desc.push(" • " + buckets[3].label + ": " + p3.toFixed(1) + "% (Standard 3-setters)");
desc.push(" • " + buckets[4].label + ": " + p4.toFixed(1) + "% (Tight 3-setters)");
desc.push(" • " + buckets[5].label + ": " + p5.toFixed(1) + "% (Absolute Marathons)");

if (p5 >= 15.0) {
desc.push(" ⚠️ Look closely at the " + buckets[5].label + " bucket. The simulation is telling you that " + p5.toFixed(1) + "% of the time, this matchup turns into a complete marathon. That massive right-side 'tail' pulls the Expected Value heavily UP.");
} else if (p0 >= 20.0) {
desc.push(" ⚠️ Look closely at the " + buckets[0].label + " bucket. The simulation sees a massive " + p0.toFixed(1) + "% chance of a quick blowout, which heavily anchors the Expected Value DOWN.");
}

return desc;
}

Step 2: Inject it into MATCH_PREVIEW
Go back up to where you just pasted the [TOTALS HIST] lines in your MATCH_PREVIEW function.
Find this block:
lines.push("[TOTALS MODES] " + (topTotals || "n/a"));
lines.push("[TOTALS HIST] line=" + lineTot + " | " + (hist || "n/a"));

Right below that, paste this new code block. This will command the script to generate that bulleted list and push it directly into your preview cell:
var histDesc = generateHistogramDescription(gamesListAdj, buckets, lineTot);
for (var k = 0; k < histDesc.length; k++) {
lines.push(histDesc[k]);
}

What happens now:
Whenever you look at a preview, you won't just see raw percentages. The script will automatically break the math out into a clean, easy-to-read list right below the raw [TOTALS HIST] line.
If the "Marathon" bucket spikes over 15%, or the "Blowout" bucket spikes over 20%, it will automatically flag that specific "tail" for you with a warning triangle so you instantly know why the total expected games shifted without having to do the math yourself!

Ensuring safety with variable scope

The syntax check is fine in Node. But to fully ensure our newly added function isn’t referencing undefined variables, we need to confirm variables like gamesListAdj, buckets, lineTot, and lines are in scope. Since they’re declared earlier in the function, they should be fine, but I’ll double-check. The only exception might be buckets, which could cause issues if it isn’t assigned before the else block, so I’ll be cautious.

Addressing undefined and syntax issues

The generator handles uncertain values for buckets, since it checks for !buckets at runtime, so it's safe. As for gamesListAdj and lineTot, they are in scope and already defined. Checking for any left-over en dashes in the bucket labels is also necessary. Now, I'll provide the link to the updated script for download.

Answer

Updated ✅ (starting from your uploaded script (4.0fix_patched_totals_hist_v4.0.txt))

  • Fixed the bucket labels in _buildLineCenteredBuckets_ by replacing all long dashes () with standard hyphens (-).
  • Added function _generateHistogramDescription_(gamesList, buckets, lineTot) at the bottom (right after the existing totals helper functions).
  • Injected the description output into MATCH_PREVIEW immediately after the [TOTALS HIST] line(s), pushing the generated lines into lines.

Download the updated script TXT

Post-update checks (done after editing)

  • Syntax: ✅ Parsed/compiled cleanly (no syntax errors).
  • Undefined-risk (for the new additions): ✅ The new call site references gamesListAdj, buckets, and lineTot in the same scope where [TOTALS HIST] is already being printed, and _generateHistogramDescription_ is defined as a hoisted function declaration, so it’s available when called.
