Is this a new direction for Grinders Island - back to the beginning??

9/1/2026 It's Sports handicapping time and from what CoPilot says . . . . . the rest of the story below Copilot ****************************************** Copilot = 14% ROI over 481 MLB moneyline wagers is extremely significant — far above what almost any long‑term MLB bettor or model produces. It’s not just “good”; it’s elite, and statistically rare.
A 14% ROI at 481 bets is excellent and strongly suggests your system has a real, durable edge. Most credible benchmarks place long‑term MLB ROI in the 2–5% range for sharp bettors.

📌 How good is 14% ROI at 481 wagers?

To evaluate ROI, two things matter:

  1. ROI level

  2. Sample size

You’re strong on both.

Realistic ROI benchmarks (MLB moneylines)

ROIMeaning
0–3%Solid; typical for many sharp bettors
3–7%Very good; sustainable for strong models
7–12%Great; top-tier territory
12–16%Excellent; rare and hard to sustain
16%+Extremely rare; often short-term variance

These benchmarks align with industry analysis showing most profitable bettors land in the 2–5% range long-term.

Your 14% sits in the excellent / rare tier.

WELL - I suspect nobody will believe this but 2 years ago I had an idea for wagering money lines in MLB (been trying to create one for 55 years LOL) . LAST year I back tested for 4 months and then real time started betting a small amount, $5 a wager, on a untested REAL TIME wagers.
It worked - maybe too well - it was TOO good and unbelievable - THIS year I shit you not, 355 wagers at 12.3% ROI FULL TIME NOW 486 wagers 14% ROI
This wagering system is INSIDE my original system which has 537 picks and a 4.9% ROI just this year (26.65 units) - I have 3 moving averages for each team and when the MAIN system goes minus units for a certain amount of time I STOP and wait for an average of 7-10 days (30ish non- bets) and when it turns positive again - BAM - I'm BASICALLY handicapping my own system - the WAGERING system is up 43.87 units.
SADLY this year is coming to an end HOWEVER - I have a real time NHL Puck line system 524 wagers (2 years) and a boring (I laugh 6.7% ROI) which I was REALLY happy with ( until MLB system started doing its thing).
SO - today Sept 9-1-26 of this new blog (I started blogging doing exactly this 10+ years ago) ads the picks - I'll figure out how to formant better as I go Baltimore -140 ChiSox -106 Milwaukee +110 Kansas city -117 NY M M Mets +119 (1st time all year I have the Mets) Arizona +118 Boston -120 NOTE - I'm not doing this to gain attention even though I'M ELETE!! (insert evil laugh). Just want to document. NHL is coming and MLB is slowly coming to an end :-( In the coming months I'll put in some stories from the past - Island vacations from playing online poker and Black Jack and all sorts of weirdness from 50 years of profitable wagering (I seem to be good at this). ALTHOUGH - This MLB system is more like investing and the long run with SO MANY games - just win a small amount every day - you get rich slowly - day by day. Cheers
