The difference from V1 and V1mini (the same for V2) is the calc of min lot.
With V1 we have:

minlot=Balance/6000/100

...so every 6000$ on your account, you double the lot
Example: start with 3000$ on your account--> minlot=0.01
when your accont is 6000$ --> minlot=0.02
when your account is 12000$ --> minlot=0.03
...and so on!

with V1mini we have:

minlot=Balance/600/100

...so every 600$ on your account, you double the lot
Example: start with 300$ on your account--> minlot=0.01
when your accont is 600$ --> minlot=0.02
when your account is 1200$ --> minlot=0.03
...and so on!

There is another difference about Maxlot:

On V1:
if (AccountBalance()>6000) MaxLot=MathFloor(AccountBalance()/40)/100;

On V1mini:
if (AccountBalance()>6000) MaxLot=MathFloor(AccountBalance()/4)/100;

...there is an error here ^ .(I suppose). The correct is 600 and not 6000!

Like you see, both V1 and V1mini start with minlot=0.01, but there is a big difference about the margin free because (the margin used for 0.01 is the same) on account with 3000$ we have enought money for trade another lot (0.02,0.04 and so on...) instead on mini account with 300$ there is a dangerous situation.
Make your calc!!!
