Hi, Arnie,

Thanks for your effort, I will review it, did review the first 2 batch files thoroughly, appreciate you even pointed out some typos for the charts/pictures. And I also did a few more miner change for content as well. 

As you suggested, I may combine them as one single file, send it back via the sample summiting link (hopefully it works) for your final check. 

Have a great weekend,
Pearl
