Doesn't prove a thing. Honda has never had a good understanding of tyres IMO.
Agree on that. That is just another prove to me that team-takeover is always a gamble and rarely can the new team continue where the previous ends. Brawn was the exception because esentially the new car was finished before they taked over. You can't be sure if they were even collecting the data in proper way.

On the other hand, in a sense RBR had used Michelins, Bridgestones, then moved on to slicks (which have a different balance) and now this year's slicks.
Yes, but what is that experience compared let's say to Ferrari/McL/Williams. They have almost every data for every tyre on any track with almost any conditions (hot,cold,rain).
10 years for RBR is not enough to do this, and their data is mainly for grooved tyres. Sure they have enough data for Jerez or Barcelona, but not for other tracks. I'm not a tyre expert, but I'm a computer programmer for 20 years. I know how you can extract data from huge databases. If you have enough data, you can search for similar behaviours amongst different tyres, and find solutions based on that. Even it doesn't matter if it's another manufacturer. You can find similarities and find strategy for development. This is only true if teams were enough aware back in old days, and backed up all that data when the use of computers were not that common in F1. Maybe some teams only have that in papers, or they don't keep all the data before the grooved-tyres era.
It's true not only for tyres, but for any measurable thing in F1. Measuring something precisely is a very delicate thing, it's a science. You have to measure things in same place, same time, with same instrument to eliminate errors. In a case of team takeover I'm not sure that all that information can be transferred, especially for older databases.
