Understanding「知見ばかりだった」


A person is commenting about his experience working with two well known
writers:

> あのニ人は創作能力で言えば日本で指折りのクリエイターだ
>
> 俺じゃ逆立ちしても出てこない知見ばかりだったよ

I have trouble understanding the 知見ばかりだった part. I guess 知見 refers to a person
who watch and learn? What nuance does ばかりだった add? Also why it is in past
tense?




[知見](https://dictionary.goo.ne.jp/word/en/%E7%9F%A5%E8%A6%8B/#je-47726) is
knowledge itself rather than person.

Whatever the topic is, the speaker is saying that all the knowledge shared by
those two people is not something the speaker can easily come up with. In the
particular context, it could be understood as ideas proposed by the two
people.

ばかり is used in the standard way
([#2](https://dictionary.goo.ne.jp/word/en/%E3%81%B0%E3%81%8B%E3%82%8A/#je-60083)),
meaning _all/most of the ideas (were something that wouldn't come out from
me)_.

だった is used because it is referring to the past experience (I assume the two
people are not present in the conversation).
