How many file transfers would be optimal? I have different rules in my mind for each cases.

**Example 1**

**Track: ~50 seconds (first lap ~60)**

**N x 2 laps relay**

pipsqueak A: 2 laps (~1:50)

pipsqueak B: 2 laps (~3:30)

pipsqueak A: 2 laps (~5:10)

pipsqueak B: 2 laps (~6:50)

pipsqueak A: ~1.5 laps

pipsqueak A: 5.5 laps, pipsqueak B: 4 laps, 4 transfers (too much), not enough balanced

**N x 3 laps relay**

pipsqueak A: 3 laps (~2:40)

pipsqueak B: 3 laps (~5:10)

pipsqueak A: 3 laps (~7:40)

it's useless to forward...

pipsqueak A: 6 laps, pipsqueak B: 3 laps, 2 transfers, not enough balanced

**N x 4 laps relay**

pipsqueak A: 4 laps (~3:30)

pipsqueak B: 4 laps (~6:50)

pipsqueak A: almost 1.5 laps

pipsqueak A: 5.5 laps, pipsqueak B: 4 laps, 2 transfers, not enough balanced

**N x 5 laps relay**

pipsqueak A: 5 laps (~4:20)

pipsqueak B: 4.5 laps

1 transfer, quite balanced, maybe a bit boring

**Example 2**

**Track: ~40 seconds (first lap ~50)**

**N x 2 laps relay**

pipsqueak A: 2 laps (~1:30)

pipsqueak B: 2 laps (~2:50)

pipsqueak A: 2 laps (~4:10)

pipsqueak B: 2 laps (~5:30)

pipsqueak A: 2 laps (~6:50)

pipsqueak B: almost 2 laps

pipsqueak A: 6 laps, pipsqueak B: almost 6 laps, 5 transfers (way too much), balanced

**N x 3 laps relay**

pipsqueak A: 3 laps (~2:10)

pipsqueak B: 3 laps (~4:10)

pipsqueak A: 3 laps (~6:10)

pipsqueak B: almost 3 laps

pipsqueak A: 6 laps, pipsqueak B: almost 6 laps, 3 transfers, balanced

**N x 4 laps relay**

pipsqueak A: 4 laps (~2:50)

pipsqueak B: 4 laps (~5:30)

pipsqueak A: almost 4 laps

pipsqueak A: almost 8 laps, pipsqueak B: 4 laps, 2 transfers, forget it...

**N x 5 laps relay**

pipsqueak A: 5 laps (~3:30)

pipsqueak B: 5 laps (~6:50)

pipsqueak A: almost 2 laps

pipsqueak A: almost 7 laps, pipsqueak B: 5 laps, 2 transfers (useless), the second transfer would give a strange taste.
