Spouse visa extension FLR(FM) changed from 5 year to 10 year

Spouse visa extension under FLR(FM) Visa granted But changed from 5 year route to 10 year route
I applied for my wife's visa extension under 5 year route FLR(FM) Under category A as we both are working. We provided our salary proofs but immigration office did not accepted my employment as i am the only director of the business. So the immigration officer asked for further documents from my business to consider my earnings. They asked for Comapny's CT600 and considering my earning during that period which was whole last year. My wife was not working that time and also i was studying and working as well. Therefore the immigration officer consider that financial requirement is not met under the paragraphs of E-LTRP 3.1, 3.2 & 3.3 of the immigration rules and R-LTRP-1.1 (a), (b) and (c). The immigration officer consider the application under R-LTRP.1.1 (a), (b) and d of Appendix FM which include the exceptions paragraph EX.1 (a) and(b). They granted the leave under the immigration rules under D-LTRP.1.2 of Appendix FM. Basically they change the status from 5 year route to 10 year route.
Q1. Under the 10 year route - Is it started from the beginning or the previous period is counted?
Q2. Our circumstances are better now and if we apply again to get it returned back to 5 year route, the previous period of stay will be considered?

Q1- I think you can apply for ILR after 10 years legal stay in any immigration category individually or jointly with others as long 10 years legally are completed . 2:- I think if you apply again and get spouse LTR , your clock of 5 years will start from the day you get Spouse LTR meaning previous 30 months spent on spouse LTR will not be counted . However I could be wrong on this points other senior members can answer better .
