FM24 Realistic Injury Frequency Rebalance

This is a complete rework of the FM24 injury frequency system based on how football actually works in real life — both in matches and training.

The update is based on football research data found by ai agents to provide a realistic injury frequency of each type and a realistic distribution of injuries between match and training.

The rebalance takes into account:

- Player collisions and physical contact
- Tackles (made and received)
- Sprinting at maximum intensity
- Sudden changes of direction
- Jumping and landing (headers, goalkeepers, aerial duels)
- Falls (back, shoulder, head impact)
- Gym/strength sessions
- Repetitive ball striking
- Shot blocking and goalkeeper impact
- Seasonal fatigue accumulation
- Minor off-field illnesses (flu, virus, food poisoning)

What This Changes

Instead of random-feeling injury distribution, this system creates logical frequency layers:

1. Minor & Contact Injuries Are More Common
Bruises, stubbed toes, tight muscles, sprains and small strains now occur at realistic levels. Football is a contact sport — players constantly collide, fall and get stepped on.

2. Sprint & Fatigue Injuries Are Properly Represented
Hamstrings, groin, thigh and calf issues reflect the explosive nature of modern football. High intensity and fixture congestion now feel more believable.

3. Serious Injuries Remain Rare
ACL tears, fractures, spinal injuries and catastrophic damage stay extremely uncommon — as they should be in a balanced game environment.

4. Illness Is Realistic but Not Overpowered
Flu and viruses occur occasionally during the season without breaking squad stability.

Overall Goal

The objective was not to increase injury chaos, but to create:

- Better immersion
- More believable squad management
- Realistic rotation importance
- Logical injury patterns
- A balance between realism and gameplay enjoyment

This mod makes FM24 feel closer to real football without turning it into an injury simulator.
