quantitative analysis

and if the learning rate continues what do we use?

What you have written in your first post is correct. With regard to your second post, the time taken for the new contract (and therefore the cost) is the difference between the time for the total number of units they will have made less the time for the number of units before doing the new contract. I show this in my free lectures on learning curves.

thank you

can you please tell me the key points to note when interpreting 1 material mix and yield variance 2 planning and operational variance 3 sales mix and sales quantity variance I have watched your lectures on variance but still I see it difficult.

Please start a new thread when you are asking about different topic. I can't tell you the key points because everything in the lectures is relevant. All you can do is watch the lectures again and keep practicing questions in your Revision Kit.
