This is estimated because I only have some render records and old files from my hard drives that I recovered recently.

The exact dates of when I started and when I actually worked on my Blender skills are impossible to tell. I always used a ZIP version of Blender that I installed manually. Later, around 2017–2018, I switched to the Windows Store version of Blender.

I did try my luck with Steam Blender, but the updates were always too late for me. I would read about a release, and with the Microsoft Store and ZIP install, I always got them first, so I never fully switched.

To be fair, probably 99% of these hours were just goofing off, messing with the features to figure them out. :P

1. Low Usage Phase (First 5 Years)

• Sessions per week: 3

• Hours per session: 5

• Weeks per year: 52

• Total hours per year:
  3 × 5 × 52 = 780 hours

• Total for 5 years:
  780 × 5 = 3,900 hours

2. Normal Usage Phase (Next 9 Years)

• Days per week: 5 (excluding 2 random break days)

• Hours per day: 4

• Weeks per year: 52

• Baseline total per year:
  5 × 4 × 52 = 1,040 hours

Adjusting for Breaks

• Computer broke: 3 months total (1 + 2 months) → 3 × 4 = 12 weeks lost

• Vacations per year: 1.5 weeks per year on average

• Total lost weeks per year:
  12/9 + 1.5 = 2.83 weeks per year

• Effective weeks per year:
  52 - 2.83 = 49.17 weeks

• Adjusted yearly total:
  5 × 4 × 49.17 = 983.33 hours

• Total for 9 years:
  983.33 × 9 = 8,850 hours

3. Recent Usage Phase (Last 1 Year, 2024-2025)

• Estimated decrease: 50% of normal usage

• Total hours for 1 year:
  983.33 × 0.5 = 491.67 hours

Final Total

3,900 + 8,850 + 491.67 = 13,241.67 hours

Rounded Total: ~13,242 hours
