Championship: point4 question

 
I have a question about Trading terms, point 4: "The minimum trade size is 0.1 lot, the maximum one is 5 lots with the step of 0.1 lot for each order."
My question is:
- How many trades of 5 lots can i open (if my account allow it) ?
- What does it mean "step of 0.1 lot for each order" ? Is it that , i can only place 0.1 lots orders till i reach 5 lots?

Thnkx for your answers

1. 3 orders of 5 lots
2. Step 0.1 means you cannot trade with 0.05, 1.26, 3.89 etc lots
