If 75% is for the LTC holders at 1:1 ratio and 25% for airdrop participants then total circulating supply is a little different than what LTC has. Are you going to adjust the total coin supply of your forked coins? And if so, what will be your total supply, mined and to be mined?
The 126,000,000 LTCP is the maximum supply. 42,000,000 LTCP will be from airdrop, 55,404,133 LTCP (currently Litecoin circulating supply) will go to LTC holders and the rest (about 28595867 LTCP) will be mineable.
