 #### 6.3.1 Daily Schedule Scattering
 
-For `FUZZY:DAILY * * *`:
+For `FUZZY:DAILY * * *` and `FUZZY:DAILY_WEEKDAYS * * *`, an implementation MUST use the **weighted daily time slot pool** to select execution time:
 
-1. Calculate hash modulo 1440 (24 hours * 60 minutes)
-2. Convert result to hour and minute components
-3. Generate cron: `<minute> <hour> * * *`
+1. Construct a weighted pool of (hour, minute) time slots using three preference tiers:
+   - **BEST** (weight 3): hours 02–05 UTC, odd minutes `{7, 13, 23, 37, 43, 53}` → 72 slots
+   - **GOOD** (weight 2): hours 10–12 UTC, minutes `[5, 54]` → 300 slots
+   - **OK** (weight 1): hours 19–23 UTC, minutes `[5, 54]` → 250 slots
+   - Total pool size: 622 slots
+2. Select slot: `index = hash(workflow_identifier) % pool_size`
+3. Extract `(hour, minute)` from the selected slot
+4. Generate cron: `<minute> <hour> * * *`  (or `* * 1-5` for weekday variant)
+
+The pool is pre-computed once. Because each tier appears proportionally in the pool, a randomly selected slot is 3× more likely to land in the BEST window than in the OK window.
 
 **Example**:
 ```
-hash("github/gh-aw/workflow.md") % 1440 = 343
-hour = 343 / 60 = 5
-minute = 343 % 60 = 43
-cron = "43 5 * * *"  (5:43 AM)
+pool_size = 622
+hash("github/gh-aw/workflow.md") % 622 = 84
+slot[84] = (hour=2, minute=23)  # BEST tier
+cron = "23 2 * * *"  (2:23 AM UTC)

-For `FUZZY:WEEKLY * * *`:
-
-1. Calculate hash modulo (7 * 24 * 60) = 10080 (week in minutes)
-2. Extract day-of-week: `day = (hash_result / 1440) % 7`
-3. Extract time: `time_in_minutes = hash_result % 1440`
-4. Convert time to hour and minute
-5. Generate cron: `<minute> <hour> * * <day>`
+For `FUZZY:WEEKLY * * *` and `FUZZY:WEEKLY:DOW * * *`:

+
+### 6.4 Peak Minutes Avoidance
+
+To reduce scheduling collisions with other commonly-scheduled cron jobs, implementations MUST apply two minute-avoidance passes after computing the raw scattered minute value.
+
+#### 6.4.1 Hour Boundary Avoidance (`avoidHourBoundary`)
+
+Minutes near the hour boundary (0–4 and 55–59) are subject to elevated load on GitHub Actions infrastructure, especially at 00:00 UTC.
+
+An implementation MUST remap minute values as follows:
+
+| Input range | Output |
+|-------------|--------|
+| [0, 4] | minute + 5 |
+| [55, 59] | minute − 5 |
+| [5, 54] | unchanged |
+
+This ensures all generated minute values are in [5, 54].
 
-1. Calculate hash modulo 1440
-2. Convert to hour and minute
-3. Generate cron: `<minute> <hour> */14 * *`
+**Scope**: Applied to ALL targeted-scatter patterns (DAILY_AROUND, DAILY_BETWEEN, WEEKLY_AROUND, and their weekday variants).
 
-For `FUZZY:TRI-WEEKLY * * *`:
+#### 6.4.2 Peak Minutes Avoidance (`avoidPeakMinutes`)
 
-1. Calculate hash modulo 1440
-2. Convert to hour and minute
-3. Generate cron: `<minute> <hour> */21 * *`
+Known high-traffic periods require avoidance of minutes that fall within ±3 of the peak minute values.
 
-### 6.4 Algorithm Requirements
+An implementation MUST apply the following remapping **after** `avoidHourBoundary`:
+
+| Condition | Avoid range | Replacement |
+|-----------|-------------|-------------|
+| hour ∈ [6, 9] AND minute ∈ [27, 33] | [27, 33] | 34 |
+| hour ∈ [14, 18] AND minute ∈ [12, 18] | [12, 18] | 19 |
+| hour ∈ [14, 18] AND minute ∈ [42, 48] | [42, 48] | 49 |
+
+**Rationale**:
+- **EU morning peak** (06:00–09:59 UTC): `:30` is a commonly-used cron minute. Staying 3 minutes away (avoiding [27,33]) reduces collisions.
+- **US business hours** (14:00–18:59 UTC): `:15` and `:45` are quarter-hour marks widely used by monitoring and reporting cron jobs. Staying 3 minutes away (avoiding [12,18] and [42,48]) reduces collisions.
+
+**Application order**: `avoidHourBoundary` MUST be applied before `avoidPeakMinutes`.
+
+**Scope**: `avoidPeakMinutes` applies only to targeted-scatter patterns. Full-day scatter patterns that use the weighted pool (Section 6.3.1) already avoid peak windows by construction, since the pool does not include EU peak hours (06–09) or US peak hours (14–18).
+
+**Example**:
+```
+FUZZY:DAILY_AROUND:14:00, workflow "my-scanner"
+  Raw scattered time: 14:28
+  Step 1 (avoidHourBoundary): 28 → 28  (no change; 28 ∈ [5,54])
+  Step 2 (avoidPeakMinutes):  28 → 34  (shifted; hour ∈ [14,18], minute 28 ∈ [27,33]
+                                          — wait, hour=14, so EU rule doesn't apply;
+                                          US :15 rule: 28 ∉ [12,18]; :45 rule: 28 ∉ [42,48])
+  → no shift needed; result: 14:28
+
+FUZZY:DAILY_AROUND:15:00, workflow "my-monitor"
+  Raw scattered time: 15:13
+  Step 1 (avoidHourBoundary): 13 → 13  (no change)
+  Step 2 (avoidPeakMinutes):  13 → 19  (shifted; hour ∈ [14,18], minute 13 ∈ [12,18])
+  → result: 15:19

+  - `avoidHourBoundary`: shifts minutes [0,4]→[5,9] and [55,59]→[50,54]
+  - `avoidPeakMinutes`: EU peak (hours 06–09) avoids ±3 min of :30 (shifts [27,33]→34); US business hours (14–18) avoids ±3 min of :15 (shifts [12,18]→19) and ±3 min of :45 (shifts [42,48]→49)
